us, ls, lts -, which are not cleared by hot reset. these write protecti on status registers are updated when fba is set, and when write protection command is entered. the followings summarize locking status. example) in default, [2:0] values are 010. -> if host executes unlock block operation, then [2:0] values turn to 100. -> if host executes lock-tight block operation, then [2:0] values turn to 001. -

(locked-tight state can be ac hieved via lock-tight command which follows lock command) only one block can be released from lock st ate to unlock state with unlock command and addresses. the unlocked block can be cha nged with new lock command. therefore, each block has its own lock/unlock/lock-tight state. if any blocks are changed to locked-tight state, the all block unlo ck command will fail. in orde r to use all block unlock comma nd again, a cold reset is needed. 3.4.3.2 locked nand arra y write protection state a locked block cannot be programmed or erased. all blocks default to a locked state fo llowing a cold or warm reset. unlocked bl ocks can be changed to locked using the lock block command. the status of a locked block can be changed to unl ocked or locked-tight using t he appro- priate software command. unlock command sequence: start block address+unlock block command (0023h) unlocked all block unlock command sequence: start block address(000h)+all block unlock command (0027h) note : even though sba is fixed to 000h, unlock will be done for all block. unlocked lock command sequence: start block address+lock block command (002ah) locked -

(refer to 2.8.13) the host can access onenand during synchr onous burst block read in between every 1-p age of read cycle. when host accesses dat- arams, the start address of datarams must be a multiple of 4 in order to prevent from data corruption. in doing this, int pin or bit is used as indicator signal. thus, before host reads 1-page data from dataram, host must confirm int pin or bit return low to high, and t hen enable ce to read 1-page of data. and when host read operation for this 1-page is done, int will aut omatically turn low. note that int au to mode is a mandatory option for synchronous burst block read, and we must always be set high throughout this opeartion. therefore, the steps are as follows; 1. host will deassert ce of onenand after checking the i ndicator(int pin / bit) turn low. 2. and then assert the ce of other device to perform another operation. 3. then disable this other device by deasserting ce when desired operation is done. 4. once the host confirms the int pin or bit of onenand turn low to high, host may read the data of following page by asserting ce (refer to synchronous burst block read operation timing). note that return of int pin to high implies the internal load operation from nand flash array to dataram is complete. also, whe n the host is not accessing other device, this assert/deassert of ce step is neccessary. to read data from this loaded 1 page, same 4, 8, 16, 32, cont inuous (1k word) linear burst read operation of synchronous burst read may be utilized. in conclusion, by supporting i ndicator signal such as int pin or bit, host may access other device without terminating continuo us linear syn- chronous burst block read, while using cont inuous linear burst read mode as synchronous block read within 1 block between every (n) page and (n+1) page.

and ?2x cache program? cases, int pin notif ies that only trasferring from dataram to page buffer is comp leted. this provides a hardware method of signaling the comp letion of a program, erase, or load operation. in its normal state, the int pin is high if the int polarity bit is default. in case of normal int mode, before a command is w ritten to the com- mand register, the int bit must be written to '0' so the int pi n transitions to a low state indicating start of the operation. in case of ?int auto mode?, int bit is written to ?0? automatically right after co mmand issued. upon completion of the command operation by the onen and?s inter- nal controller, int returns to a high state. int pin is a dq-type output except ?reset? and ?2x program? in dd p allowing two int outputs to be or-tied together. in case of ?reset? and ?2x program? in ddp, int pin operates as an open drain with 50k ohm. int does not float to a hi-z condition when ce is disabled or oe is dis- abled. refer to section 2.8 for additional information about int. int can be implemented by tying int to a host gpio or by continuous polling of the interrupt status register. int type (mono) int type (ddp) general operation dq type dq type reset operation (warm,hot and flash core reset) and 2x program dq type open drain (with 50kohm) - 167 - flash memory onenand2g(kfg2g16q2a-debx) onenand4g(kfh4g16q2a-debx) 7.1.1 the int pin to a host general purpose i/o int can be tied to a host gpio to detect the rising edge of int, signaling the end of a command operation. this can be configured to operate eith er synchronously or asynchronously as shown in the diagrams below. synchronous mode using the int pin when operating synchronously, int is tied directly to a host gpio. rdy coul d be conneceted as one of following guides. asynchronous mode using the int pin when configured to operate in an asynchronous mode, ce and avd of the onenand are tied to ce of the host. clk is tied to the host vss (ground). rdy is not connected. oe of the onenand and host are tied together and int is tied to a gpio. int command host onenand rdy(wait) oe clk ce rdy oe clk ce avd gpio int host onenand oe clk ce rdy oe clk ce avd gpio int handshaking mode non-handshaking mode host onenand oe vss ce rdy oe clk ce avd gpio int - 168 - flash memory onenand2g(kfg2g16q2a-debx) onenand4g(kfh4g16q2a-debx) 7.1.2 polling the interrupt register status bit an alternate method of determining the end of an operation is to continuously monitor the interrupt status register bit instead of using the int pin. when using interrupt register instead of int pin, int must be unconnected. this can be configured in either a sy nchronous mode or an asynchronous mode. synchronous mode using interrupt status register bit polling when operating synchronously, ce and avd of the onenand are tied to ce of the host, clk, oe , and dq pins on the host and onenand are tied together. rdy could be connec ted as one of following guides. asynchronous mode using interrupt status register bit polling when configured to operate in an asynchronous mode, ce and avd of the onenand are tied to ce of the host. clk is tied to the host vss (ground). rdy is not connected. oe and dq of the onenand and host are tied together. int command host onenand rdy(wait) oe clk ce rdy oe clk ce avd dq dq host onenand oe clk ce rdy oe clk ce avd dq dq handshaking mode non-handshaking mode host onenand n.c oe ce rdy oe clk ce avd dq dq vss - 169 - flash memory onenand2g(kfg2g16q2a-debx) onenand4g(kfh4g16q2a-debx) 7.1.3 determining rp value (ddp, qdp only) for general operation, int operates as normal output pin, so that tf is equivalent to tr (below 10ns). but since int operates a s open drain with 50k ohm for reset (hot/warm/nand flash core) operations case and ?2x program operation (007dh) case at ddp option, the pul l-up resistor value is related to tr(int). and appropriate va lue can be obtained with the following reference charts. note : 1) refer to chapter 2.8.10 start address register f101h ddp block diagram busy state ready vcc voh tf tr vol vss ~50k ohm int 1) vcc or vccq rp int pol = ?high?
