6.0 Input/Output Function Description
Symbol CK0-CK1 CK0-CK1 CKE0-CKE1 Type Input Description
DDR2 SDRAM
The system clock inputs. All address and command lines are sampled on the cross point of the rising edge of CK and falling edge of CK . A Delay Locked Loop (DLL) circuit is driven from the clock input and output timing for read operations is synchronized to the input clock. Activates the DDR2 SDRAM CK signal when high and deactivates the CK signal when low, By deactivating the clocks, CKE low initiates the Power Down mode or the Self Refesh mode. Enables the associated DDR2 SDRAM command decoder when low and disables the command decoder when high. When the command decoder is disabled, new commands are ignored but previous operations continue. Rank 0 is selected by S0, Rank 1 is selected by S1. Ranks are also called "Physical banks". When sampled at the cross point of the rising edge of CK and falling edge of CK, CAS, RAS, and WE define the operation to be executed by the SDRAM. Selects which DDR2 SDRAM internal bank is activated. Asserts on-die termination for DQ, DM, DQS, and DQS signals if enabled via the DDR2 SDRAM Extended Mode Register Set (EMRS). During a Bank Activate command cycle, defines the row address when sampled at the cross point of the rising edge of CK and falling edge of CK. During a Read or Write command cycle, defines the column address when sampled at the cross point of the rising edge of CK and falling edge of CK. In addition to the column address, AP is used to invoke autoprecharge operation at the end of the burst read or write cycle. If AP is high, autoprecharge is selected and BA0-BAn defines the bank to be precharged. If AP is low, autoprecharge is disabled. During a Precharge command cycle, AP is used in conjunction with BA0-BAn to control which bank(s) to precharge. If AP is high, all banks will be pecharged regardiess of the state of BA0BAn inputs. If AP is low, then BA0-BAn are used to define which bank to precharge. Data Input/Output pins. The data write masks, associated with one data byte. In Write mode, DM operates as a byte mask by allowing input data to be written if it is low but blocks the write operation if it is high. In Read mode, DM lines have no effect. The data strobes, associated with one data byte, sourced with data transfers. In Write mode, the data strobe is sourced by the controller and is centered in the data window. In Read mode, the data strobe is sourced by the DDR2 SDRAMs and is sent at the leading edge of the data window. DQS signals are complements, and timing is relative to the crosspoint of respective DQS and DQS If the module is to be operated in single ended strobe mode, all DQS signals must be tied on the system board to VSS and DDR2 SDRAM mode registers programmed appropriately. Power supplies for core, I/O, Serial Presence Detect, and ground for the module. This is a bidirectional pin used to transfer data into or out of the SPD EEPROM. A resistor must be connected to VDD to act as a pull up. This signal is used to clock data into and out of the SPD EEPROM. A resistor may be connected from SCL to VDD to act as a pull up. Address pins used to select the Serial Presence Detect base address. The TEST pin is reserved for bus analysis tools and is not connected on normal memory modules(SODIMMs).

Units V V V V C Notes 1 1 1 1 1, 2
Note : 1. Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. 2. Storage Temperature is the case surface temperature on the center/top side of the DRAM. For the measurement conditions, please refer to JESD51-2 standard.

Notes 5
Note : There is no specific device VDD supply voltage requirement for SSTL-1.8 compliance. However under all conditions VDDQ must be less than or equal to VDD. 1. The value of VREF may be selected by the user to provide optimum noise margin in the system. Typically the value of VREF is expected to be about 0.5 x VDDQ of the transmitting device and VREF is expected to track variations in VDDQ. 2. Peak to peak AC noise on VREF may not exceed +/-2% VREF(DC). 3. VTT of transmitting device must track VREF of receiving device. 4. AC parameters are measured with VDD, VDDQ and VDDL tied together. 5. SO-DIMMs that include an optional temperature sensor may require a restricted VDDSPD operating voltage range for proper operation of the temperature sensor. Refer to the thermal sensor specification for details regarding the supported voltage range. All other functions of the SO-DIMM SPD are supported across the full VDDSPD range.

Note : 1. Operating Temperature is the case surface temperature on the center/top side of the DRAM. For the measurement conditions, please refer to JESD51.2 standard. 2. At 85 - 95 C operation temperature range, doubling refresh commands in frequency to a 32ms period ( tREFI=3.9 us ) is required, and to enter to self refresh mode at this temperature range, an EMRS command is required to change internal refresh rate.

Note : 1. Input waveform timing is referenced to the input signal crossing through the VIH/IL(AC) level applied to the device under test. 2. The input signal minimum slew rate is to be maintained over the range from VREF to VIH(AC) min for rising edges and the range from VREF to VIL(AC) max for falling edges as shown in the below figure. 3. AC timings are referenced with input waveforms switching from VIL(AC) to VIH(AC) on the positive transitions and VIH(AC) to VIL(AC) on the negative transitions.
