(for the addition of operation mode in future) 5 HM5316123B Series ct du ro LP EO CAS (input pin): Column address and DSF1 signals are fetched into chip at the falling edge of CAS, which determines the operation mode of the HM5316123B. CAS controls output impedance of I/O in RAM. A0 - A8 (input pins): Row address (AX0 - AX8) is determined by A0 - A8 level at the falling edge of RAS. Column address (AY0 - AY7) is determined by A0 - A7 level at the falling edge of CAS. In transfer cycles, row address is the address on the word line which transfers data with SAM data register, and column address is the SAM start address after transfer. WEU and WEL (Input pins): WEU and WEL pins have two functions at the falling edge of RAS and after. When either WEU or WEL is low at the falling edge of RAS, the HM5316123B turns to mask write mode. According to the I/O level at the time, write on each I/O can be masked. (WEU and WEL levels at the falling edge of RAS is don't care in read cycle.) When both WEU and WEL are high at the falling edge of RAS, a no mask write cycle is executed. After that, WEU and WEL switch read/write cycles. Both WEU and WEL must be held high in a read cycle. In a transfer cycle, the direction of transfer is determined by WEU and WEL levels at the falling edge of RAS. When either WEU or WEL is low, data is transferred from SAM to RAM (data is written into RAM), and when both WEU and WEL are high, data is transferred from RAM to SAM (data is read from RAM). I/O0 - I/O15 (input/output pins): I/O pins function as mask data at the falling edge of RAS (in mask write mode). Data is written only to high I/O pins. Data on low I/O pins are masked and internal data are retained. After that, they function as inut/output pins as those of a standard DRAM. In block write cycle, they function as column mask data at the falling edges of CAS, and WEU or WEL. 6 Preliminary Data Sheet E0160H10 DT/OE (input pin): DT/OE pin functions as DT (data transfer) pin at the falling edge of RAS and as OE (output enable) pin after that. When DT is low at the falling edge of RAS, this cycle becomes a transfer cycle. When DT is high at the falling edge of RAS, RAM and SAM operate independently. SC (input pin): SC is a basic SAM clock. In a serial read cycle, data outputs from an SI/O pin synchronously with the rising edge of SC. In a serial write cycle, data on an SI/O pin at the rising edge of SC is fetched into the SAM data register. SE (input pin): SE pin activates SAM. When SE is high, SI/O is in the high impedance state in serial read cycle and data on SI/O is not fetched into the SAM data register in serial write cycle. SE can be used as a mask for serial write because the internal pointer is incremented at the rising edge of SC. SI/O0 - SI/O15 (input/output pins): SI/Os are input/output pins in SAM. Direction of input/output is determined by the previous transfer cycle. When it was a read transfer cycle, SI/O outputs data. When it was a masked write transfer cycle, SI/O inputs data. DSF1 (input pin): DSF1 is a special function data input flag pin. It is set to high at the falling edge of RAS when new functions such as color register and mask register read/write, split transfer, and flash write, are used. DSF2 (input pin): DSF2 is also a special function data input flag pin. This pin is fixed to low level in all operations of the HM5316123B. QSF (output pin): QSF outputs data of address A7 in SAM. QSF is switched from low to high by accessing address 127 in SAM and from high to low by accessing address 255 in SAM. HM5316123B Series ct du ro LP EO Operation of HM5316123B RAM Port Operation RAM Read Cycle (DT/OE high, CAS high and DSF1 low at the falling edge of RAS, DSF1 low at the falling edge of CAS) Row address is entered at the RAS falling edge and column address at the CAS falling edge to the device as in standard DRAM. Then, when WEU or WEL is high and DT/OE is low while CAS is low, the selected address data outputs through I/O pin. At the falling edge of RAS, DT/OE and CAS become high to distinguish RAM read cycle from transfer cycle and CBR refresh cycle. Address access time (t AA ) and RAS to column address delay time (t RAD ) specifications are added to enable fast page mode. RAM Write Cycle (Eraly Write, Delayed Write, Read-Modify-Write) (DT/OE high, CAS high and DSF1 low at the falling edge of RAS, DSF1 low at the falling edge of CAS) * No Mask Write Cycle (WEU and WEL high at the falling edge of RAS) When CAS is set low and either WEU or WEL is set low after RAS low, a write cycle is executed. If either WEU or WEL is set low before the CAS falling edge, this cycle becomes an early write cycle and all I/O become in high impedance. All 16 data are latched on the falling edge of CAS. If only one of WEU and WEL is low when CAS falls, the write will affect only those corresponding 8 bits. If the other of WEU and WEL falls at the same time in the cycle, the write will then occur for those 8 bits, with the latched data. If both WEU and WEL are set low after the CAS falling edge, this cycle becomes a delayed write cycle and all 16 data are latched on the falling edge of WEU or WEL. Byte write occures if only one of WEU or WEL falls during the cycle. I/O does not become high impedance in this cycle, so data should be entered with OE in high. If both WEU and WEL are set low after tCWD (min) and tAWD (min) after the CAS falling edge, this cycle becomes a read-modify-write cycle and enables read/write at the same address in one Preliminary Data Sheet E0160H10 cycle. In this cycle also, to avoid I/O contention, data should be input after reading data and driving OE high. * Mask Write Mode (WEU or WEL low at the falling edge of RAS) If WEU or WEL is set low at the falling edge of RAS, two modes of mask write cycle are capable. 1. In new mask mode, mask data is loaded from I/O pin and used. Whether or not an I/O is written depends on I/O level at the falling edge of RAS. The data is written in high level I/Os, and the data is masked and retained in low level I/Os. This mask data is effective during the RAS cycle. So, in page mode cycles the mask data is retained during the page access. 2. If a load mask register cycle (LMR) has been performed, the mask data is not loaded from I/O pins and the mask data stored in mask registers persistently are used. This operation is known as persistent write mask, set by LMR cycle and reset by CBRR cycle. Fast Page Mode Cycle (DT/OE high, CAS high and DSF1 low at the falling edge of RAS) High-speed page mode cycle reads/writes the data of the same row address at high speed by toggling CAS while RAS is low. Its cycle time is one third of the random read/write cycle. In this cycle, read, write, and block write cycles can be mixed. Note that address access time (tAA), RAS to column address delay time (tRAD), and access time from CAS precharge (tACP) are added. In one RAS cycle, 256-word memory cells of the same row address can be accessed. It is necessary to specify access frequency within tRASP max (100 s). 7 HM5316123B Series ct du ro LP EO Color Register Set/Read Cycle (CAS high, DT/OE high, WEU and WEL high and DSF1 high at the falling edge of RAS) In color register set cycle, color data is set to the internal color register used in flash write cycle or block write cycle. 16 bits of internal color register are provided at each I/O. This register is composed of static circuits, so once it is set, it retains the data until reset. Since color register set cycle is just as same as the usual write cycle, so read, early write and delayed write cycle can be executed. In this cycle, the HM5316123B refreshes the row address fetched at the falling edge of RAS. Mask Register Set/Read Cycle (CAS high, DT/OE high, WEU and WEL high, and DSF1 high at the falling edge of RAS) In mask register set cycle, mask data is set to the internal mask register used in mask write cycle, block write cycle, flash write cycle, masked write transfer, and masked split write transfer. 16 bits of internal mask register are provided at each I/O. This mask register is composed of static circuits, Color Register Set Cycle Flash Write Cycle RAS CAS Address Row Xi Xj WEU,WEL DT/OE DSF1 I/O Color Data *1 *1 Set color register Execute flash write into each I/O on row address Xi using color register. Note: 1. I/O Mask Data (In new mask mode) Low: Mask High: Non Mask In persistent mask mode, I/O don't care so once it is set, it retains the data until reset. Since mask register set cycle is just as same as the usual read and write cycle, so read, early and delayed write cycles can be executed. Flash Write Cycle (CAS high, DT/OE high, WEU or WEL low, and DSF1 high at the falling edge of RAS) In a flash write cycle, a row of data (256 word x 16 bit) is cleared to 0 or 1 at each I/O according to the data of color register mentioned before. It is also necessary to mask I/O in this cycle. When CAS and DT/OE is set high, WEU or WEL is low, and DSF1 is high at the falling edge of RAS, this cycle starts. Then, the row address to clear is given to row address. Mask data is as same as that of a RAM write cycle. Cycle time is the same as those of RAM read/write cycles, so all bits can be cleared in 1/256 of the usual cycle time. (See figure 1.) Flash Write Cycle Execute flash write into each I/O on row address Xj using color register. Figure 1 Use of Flash Write 8 Preliminary Data Sheet E0160H10 HM5316123B Series ct du ro LP EO Block Write Cycle (CAS high, DT/OE high and DSF1 low at the falling edge of RAS, DSF1 high and WEU or WEL low at the falling edge of CAS) In a block write cycle, 4 columns of data (4 column x 16 bit) are cleared to 0 or 1 at each I/O according to the data of color register. Column addresses A0 and A1 are disregarded. The mask data on I/Os and the mask data on column addresses can be determined independently. I/O level at the falling edge of CAS determines the address to be cleared. (See Figure 2.) The block write cycle is as the same as the usual write cycle, so early and delayed write, read-modify-write, and page mode write cycle can be executed. * No mask Mode Block Write Cycle (WEU and WEL high at the falling edge of RAS) The data on 16 I/Os are all cleared when WEU and WEL are high at the falling edge of RAS. * Mask Block Write Cycle (WEU or WEL low at the falling edge of RAS) When either WEU or WEL is low at the falling edge of RAS, the HM5316123B starts mask block write cycle to clear the data on an optional I/O. The mask data is the same as that of a RAM write cycle. High I/O is cleared, low I/O is not cleared and the internal data is retained. In new mask mode, the mask data is available in the RAS cycle. In persistent mask mode, I/O don't care about mask mode. * Column Mask (WEU or WEL low at the falling edge of CAS) Column mask data is determined by 4I/Os (I/O0, I/O1, I/O2, I/O3) level at CAS low and WEU or WEL low edge. When upper byte column mask is performed by WEL high and WEU low, column mask data are determined by 4I/Os (I/O0, I/O1, I/O2, I/O3) and other I/Os (I/O4 to I/O15) don't care.

Theses transfer cycles are set by driving CAS high and DT/OE low at the falling edge of RAS. They have following functions: (1) Transfer data between row address and SAM data register Read transfer cycle and split read transfer cycle: RAM to SAM Masked write transfer cycle and masked split write transfer cycle: SAM to RAM (2) Determine SI/O state (except for split read transfer cycle and masked split write transfer cycle) Read transfer cycle: SI/O output Masked write transfer cycle: SI/O input (3) Determine first SAM address to access after transferring at column address (SAM start address). SAM start address must be determined by read transfer cycle or masked write transfer cycle (split transfer cycle isn't available)before SAM access, after power on, and determined for each transfer cycle. (4) Use the stopping columns (boundaries) in the serial shift register. If the stopping columns have been set, split transfer cycles use the stopping RAS CAS Address DT/OE DSF1 SC Xi Yj L t SDD t SDH SI/O Yj SAM Data before Transfer columns, but any boundaries cannot be set as the start address. (5) Load/use mask data in masked write transfer cycle and masked split write transfer cycle. Read Transfer Cycle (CAS high, DT/OE low, WEU and WEL high and DSF1 low at the falling edge of RAS) This cycle becomes read transfer cycle by driving DT/OE low, WEU and WEL high and DSF1 low at the falling edge of RAS. The row address data (256 x 16 bits) determined by this cycle is transferred to SAM data register synchronously at the rising edge of DT/OE. After the rising edge of DT/OE, the new address data outputs from SAM start address determined by column address. In read transfer cycle, DT/OE must be risen to transfer data from RAM to SAM. This cycle can access SAM even during transfer (real time read transfer). In this case, the timing tSDD (min) specified between the last SAM access before transfer and DT/OE rising edge and tSDH (min) specified between the first SAM access and DT/OE rising edge must be satisfied. (See figure 3.) When read transfer cycle is executed, SI/O becomes output state by first SAM access. Input must be set high impedance before tSZS (min) of the first SAM access to avoid data contention. Yj + 1 SAM Data after Transfer Figure 3 Real Time Read Transfer Preliminary Data Sheet E0160H10 11 HM5316123B Series ct du ro LP EO Masked Write Transfer cycle (CAS high, DT/OE low, WEU or WEL low, and DSF1 low at the falling edge of RAS) Masked write transfer cycle can transfer only selected I/O data in a row of data input by serial write cycle to RAM. Whether one I/O data is transferred or not depends on the corresponding I/O level (mask data) at the falling edge of RAS. This mask transfer operation is the same as a mask write operation in RAM cycles, so the persistent mode can be supported. The row address of data transferred into RAM is determined by the address at the falling edge of RAS. The column address is specified as the first address for serial write after terminating this cycle. Also in this cycle, SAM access becomes enabled after tSRD (min) after RAS becomes high. SAM access is inhibited during RAS low. In this period, SC must bot be risen. Data transferred to SAM by read transfer cycle or split read transfer cycle can be written to other addreses of RAM by write transfer cycle. However, the adddress to write data must be the same as that of the read transfer cycle or the split read transfer cycle (row address AX8) Split Read Transfer Cycle (CAS high, DT/OE low, WEU and WEL high and DSF1 high at the falling edge of RAS) To execute a continuous serial read by real time read transfer, the HM5316123B must satisfy SC and DT/OE timings and requires an external circuit to detect SAM last address. Split read transfer cycle makes it possible to execute a continuous serial read without the above timing limitation. The HM5316123B supports two types of split register operation. One is the normal split register operation to split the data register into two halves. The other is the boundary split register operation using stopping columns described later. Figure 4 shows the block diagram for the normal split register operation. SAM data register (DR) consists of 2 split buffers, whose organizations are 128-word x 16-bit each. Let us suppose that data is read from upper data reagister DR1 (The row address AX8 is 0 and SAM address A7 is 1.). When split read transfer is executed setting row address AX8 to 0 and SAM start addresses A0 to A6, 128-word x 16-bit data are transferred from RAM to the lower data register DR0 (SAM 12 Preliminary Data Sheet E0160H10 address A7 is 0) automatically. After data are read from data register DR1, data start to be read from SAM start addresses of data register DR0. If the next split read transfer isn't executed while data are read from data register DR0, data start to be read from SAM start address 0 of DR1 after data are read from data register DR0. If split read transfer is executed setting row address AX8 to 1 and SAM start addresses A0 to A6 while data are read from data register DR1, 128-word x 16-bit data are transferred to data register DR2. After data are read from data register DR1, data start to be read from SAM start addresses of data register DR2. If the next split read transfer isn't executed while data is read from data register DR2, data start to be read from SAM start address 0 of data register DR1 after data are read from data register DR2. In split read data transfer, the SAM start address A7 is automatically set in the data register, which isn't used. The data on SAM address A7, which will be accessed next, outputs to QSF, QSF is switched from low to high by accessing SAM last address 127 and from high to low by accessing address 255. Split read transfer cycle is set when CAS is high, DT/OE is low, WEU and WEL is high and DSF1 is high at the falling edge of RAS. The cycle can be executed asyncronously with SC. However, HM5316123B must be satisfied tSTS (min) timing specified between SC rising (Boundary address) and RAS falling. In split transfer cycle, the HM5316123B must satisfy tRST (min), tCST (min) and tAST (min) timings specified between RAS or CAS falling and column address. (See figure 5.) In split read transfer, SI/O isn't switched to output state. Therefore, read transfer must be executed to switch SI/O to output state when the previous transfer cycle is masked write transfer cycle or masked split write transfer cycle. SAM start address must be set in every split read transfer cycle.

Figure 5 Limitation in Split Transfer Preliminary Data Sheet E0160H10 13 HM5316123B Series ct du ro LP EO Masked Split Write Transfer Cycle (CAS high, DT/OE low, WEU or WEL low and DSF1 high at the falling edge of RAS) A continuous serial write cannot be executed because accessing SAM is inhibited during RAS low in write transfer. Masked split write transfer cycle makes it possible. In this cycle, tSTS (min), tRST (min), tCST (min) and tAST (min) timings must be satisfied like split read transfer cycle. And it is impossible to switch SI/O to input state in this cycle. If SI/O is in output state, masked write transfer cycle should be executed to switch SI/O into input state. Data transferred to SAM by read transfer cycle or split read transfer cycle can be written to other addresses of RAM by masked split write transfer cycle. However, masked write transfer cycle must be executed before split write transfer cycle. And in this masked split write transfer cycle, the MSB of row address (AX8) to write data must be the same as that of the read transfer cycle or the split read transfer cycle. Column size 64 bit Boundaries (B6) (Y1) (Y3) (Y2) Start Jump 1 Jump 2 Lower SAM 128 bits Upper SAM 128 bits Stopping Column in Split Transfer Cycle The HM5316123B has the boundary split register operation using stopping columns. If a CBRS cycle has been performed, split transfer cycle performs the boundary operation. Figure 6 shows an example of boundary split register. (Boundary code is B6.) First of all a read data transfer cycle is executed, and SAM start addresses A0 to A7 are set. The RAM data are transferred to the SAM, and SAM serial read starts from the start address (Y1) on the lower SAM. After that, a split read transfer cycle is executed, and the next start address (Y2) is set. The RAM data are transferred to the upper SAM. When the serial read arrive at the first boundary after the split read transfer cycle, the next read jumps to the start address (Y2) on the upper SAM (jump 1) and continues. Then the second split read transfer cycle is executed, and another start address (Y3) is set. The RAM data are transferred to the lower SAM. When the serial read arrive at the other boundary again, the next read jumps to the start address (Y3) on the lower SAM. In stopping column, split transfer is needed for jump operation between lower SAM and upper SAM.

A0, A1, and A7: don't care 2. *: don't care Stopping Column Set Cycle (CBRS) No Reset CBR Cycle (CBRN) This cycle becomes stopping column set cycle by driving CAS low, WEU or WEL low, DSF1 high at the falling edge of RAS. Stopping column data (boundaries) are latched from address inputs on the falling edge of RAS. To determine the boundary, A2 to A6 can be used and don't care A0, A1, and A7. In the HM5316123B, 6 types of boundary (B2 to B7) can be set including the default case. (See stopping column boundary table.) If A2 to A5 are set to high and A6 is set to low, the boundaries (B6) are selected. Figure 6 shows the example. The stop address that is set by the CBRS is used from next split transfer cycle. Once a CBRS is executed, the stopping column operation mode continues until CBRR. Register Reset Cycle (CBRR) This cycle becomes no reset CBR cycle (CBRN) by driving CAS low, WE high and DSF1 high at the falling edge of RAS. The CBRN can only execute the refresh operation. Byte Control (WEU, WEL) This cycle becomes register reset cycle (CBRR) by driving CAS low, WEU and WEL high, and DSF1 low at the falling edge of RAS. A CBRR can reset the persistent mask operation and stopping column operation, so the HM5316123B becomes the new mask operation and boundary code B7. When a CBRR is executed for stopping column operation reset and split transfer operation, it need to satisfy tSTS (min) and tRST (min) between RAS falling and SC rising for correct SAM read/write operation. In a write cycle, when WEL set low and WEU set high, I/O0 to I/O7 become write mode and I/O8 to I/O15 become no write mode, and when WEL set high and WEU set low, I/O0 to I/O7 become no write mode and I/O8 to I/O15 become write mode. The write cycle that byte control is capable are RAM write cycle, block write cycle, load write mask register cycle and load color register cycle. The byte control write cycle is capable to execute early write, delay write, read-modify-write and page mode. But write mask in new mask mode, flash write, transfer and refresh cycle can not execute byte control. Preliminary Data Sheet E0160H10 15 HM5316123B Series SAM Port Operation Serial Read Cycle ct du ro LP EO Refresh RAM Refresh SAM port is in read mode when the previous data transfer cycle is a read transfer cycle. Access is synchronized with SC rising, and SAM data is output from SI/O. When SE is set high, SI/O becomes high impedance, and the internal pointer is incremented by the SC rising. After indicating the last address (address 255), the internal pointer indicates address 0 at the next access. Serial Write Cycle If previous data transfer cycle is masked write transfer cycle, SAM port goes into write mode. In this cycle, SI/O data is fetched into data register at the SC rising edge like in the serial read cycle. If SE is high, SI/O data isn 't fetched into data register. The internal pointer is incremented by the SC rising, so SE high can be used as mask data for SAM. After indicating the last address (address 255), the internal pointer indicates address 0 at the next access. SAM Refresh 16 Preliminary Data Sheet E0160H10 RAM, which is composed of dynamic circuits, requires refresh cycle to retain data. Refresh is executed by accessing all 512 row addresses within 8 ms. There are three refresh cycles: (1) RAS-only refresh cycle, (2) CAS-before-RAS (CBRN, CBRS, and CBRR) refresh cycle, and (3) Hidden refresh cycle. Besides them, the cycles which activate RAS, such as read/write cycles or transfer cycles, can also refresh the row address. Therefore, no refresh cycle is required when all row addresses are accessed within 8 ms. (1) RAS-Only Refresh Cycle: RAS-only refresh cycle is executed by activating only the RAS cycle with CAS fixed to high after inputting the row address (= refresh address) from external circuits. To distinguish this cycle from a data transfer cycle, DT/OE must be high at the falling edge of RAS. (2) CBR Refresh Cycle: CBR refresh cycle (CBRN, CBRS and CBRR) are set by activating CAS before RAS. In this cycle, the refresh address need not to be input through external circuits because it is input through an internal refresh counter. In this cycle, output is in high impedance and power dissipation is lowered because CAS circuits don't operate. (3) Hidden Refresh Cycle: Hidden refresh cycle executes CBR refresh with the data output by reactivating RAS when DT/OE and CAS keep low in normal RAM read cycles. SAM parts (data register, shift resister and selector), organized as fully static circuitry, require no refresh.

Preliminary Data Sheet E0160H10 29 HM5316123B Series ct du ro LP EO 30 Preliminary Data Sheet E0160H10 Notes: 1. AC measurements assume tT = 5 ns. 2. When tRCD > tRCD (max) and tRAD > tRAD (max), access time is specified by tCAC or tAA. 3. VIH (min) and VIL (max) are reference levels for measuring timing of input signals. Transition time tT is measured between VIH and VIL. 4. Data input must be floating before output buffer is turned on. In read cycle, read-modify-write cycle and delayed write cycle, either tDZC (min) or tDZO (min) must be satisfied. 5. tOFF1 (max), tOFF2 (max), tSHZ (max) and tSLZ (min) are defined as the time at which the output acheives the open circuit condition (VOH - 100 mV, VOL + 100 mV). This parameter is sampled and not 100% tested. 6. Assume that tRCD < tRCD (max) and tRAD < tRAD (max). If tRCD or tRAD is greater than the maximum recommended value shown in this table, tRAC exceeds the value shown. 7. Measured with a load circuit equivalent to 1 TTL loads and 50 pF. 8. When tRCD > tRCD (max) and tRAD < tRAD (max), access time is specified by tCAC. 9. When tRCD < tRCD (max) and tRAD > tRAD (max), access time is specified by tAA. 10. If either tRCH or tRRH is satisfied, operation is guaranteed. 11. When tWCS > tWCS (min), the cycle is an early write cycle, and I/O pins remain in an open circuit (high impedance) condition. 12. These parameters are specified by the later falling edge of CAS or WEU and WEL. 13. Either tCDD (min) or tODD (min) must be satisfied because output buffer must be turned off by CAS or OE prior to applying data to the device when output buffer is on. 14. When tAWD > tAWD (min) and tCWD > tCWD (min) in read-modify-write cycle, the data of the selected address outputs to an I/O pin and input data is written into the selected address. tODD (min) must be satisfied because output buffer must be turned off by OE prior to applying data to the device. 15. Measured with a load circuit equivalent to 1 TTL loads and 30 pF. 16. After power-up, pause for 100 s or more and execute at least 8 initialization cycle (normal memory cycle or refresh cycle), then start operation. Hitachi recommends that least 8 initialization cycle is the CBRR for internal register reset. This CBRR need not tSTS and tRST. 17. When tSHZ and tSLZ are measured in the same VCC and Ta condition and tr and tf of SE are less than 5 ns, tSHZ < tSLZ +5 ns. This parameter is sampled and not 100% tested. 18. When both WEU and WEL go low at the same time, all 16-bits data are written into the device, WEU and WEL cannot be staggered within the same write cycles. 19. After power-up, QSF output may be High-Z, so 1 sc cycle is needed to be Low-Z it. 20. DSF2 pin is open pin, but Hitachi recommends it is fixed low in all operation for the addition mode in future.
