(number loaded = the number of locations to program minus 1. for example, if the system programs 6 address locations, then 05h should be written to the device.) the system then writes the starting address/data combination. this starting address is the first address/data pair to be programmed, and selects the ?write-buffer-page? address. all subsequent address/data pairs must fall within the elected-write-buffer-page. the ?write-buffer-page? is selected by using the addresses a21?a4. the ?write-buffer-page? addresses must be the same for all address/data pairs loaded into the write buffer. (this means write buffer programming cannot be performed across multiple ?write-buffer- pages.? this also means that write buffer programming cannot be performed across multiple sectors. if the system attempts to load programming data outside of the selected ?write-buffer-page?, the operation aborts.) after writing the starting address/data pair, the system then writes the remaining address/data pairs into the write buffer. note that if a write buffer address location is loaded multiple times, the ?address/data pair? counter is decremented for every data load operation. also, the last data loaded at a location before the ?program buffer to flash? confirm command is the data programmed into the device. it is the software's responsibility to comprehend ramifi cations of loading a write-buffer location more than once. the counter decrements for each data load operation, not for each unique write-buffer-address location. once the specified number of write buffer locations have been loaded, the system must then write the ?program buffer to flash? command at the sector address. any other address/data write combinations abort the write buffer programming operation. the write operation status bits should be used while monitoring the last address location loaded into the write buffer. this eliminates the need to store an address in memory because the system can load the last address location, issue the program confirm command at the last loaded address location, and then check the write operation status at that same address. dq7, dq6, dq5, dq2, and dq1 should be monitored to determine the device status during write buffer programming. the write-buffer ?embedded? programming operation can be suspended using the standard suspend/resume commands. upon successful completion of the write buffer programming operation, the device returns to read mode. the write buffer programming sequence is aborted under any of the following conditions: ? load a value that is greater than the page buffer size during the ?number of locations to program? step. ? write to an address in a sector different than the one specified during the write-buffer-load command. ? write an address/data pair to a different write-buffer-page than the one selected by the ?starting address? during the ?write buffer data loading? stage of the operation. ? writing anything other than the program to buffer flash command after the specified number of ?data load? cycles. the abort condition is indicated by dq1 = 1, dq7 = data# (for the ?last address location loaded?), dq6 = toggle, dq5 = 0. this indicates that the write buffer programming operation was aborted. note that the secured silicon sector, autoselect, and cfi functions are unavailable when a program

(the device ?erase suspends? all sectors selected for erasure.) reading at any address within erase-suspended sectors produces status information on dq7-dq0. the system can use dq7, or dq6, and dq2 together, to determine if a sector is actively erasing or is erase-suspended. after an erase-suspended program operation is complete, the device returns to the erase-suspend- read mode. the system can determine the status of the program operation using write operation status bits, just as in the standard program operation. in the erase-suspend-read mode, the system can also issue the autoselect command sequence. refer to write buffer programming and the autoselect for details. to resume the sector erase operation, the system must write the erase resume command. the address of the erase-suspended sector is required when writing this command. further writes of the resume command are ignored. another erase suspend command can be written after the chip has resumed erasing. program suspend/program resume commands the program suspend command allows the system to interrupt an embedded programming operation or a ?write to buffer? programming operation so that data can read from any non-suspended sector. when the program suspend command is written during a programming process, the device halts the programming operation within 15 s maximum (5 s typical) and updates the status bits. addresses are ?don't-cares? when writing the program suspend command. after the programming operation has been suspended, the system can read array data from any nonsuspended sector. the program suspend command may also be issued during a programming operation while an erase is suspended. in this case, data may be read from any addresses not within a sector in erase suspend or program suspend. if a read is needed from th e secured silicon sector area, then user must use the proper command sequences to enter and exit this region.

(the sector erase timer does not apply to the chip erase command.) when sector erase starts, dq3 switches from ?0? to ?1?. this device does not support multiple sector erase (continuous sector erase) command sequences so it is not very meaningful since it immediately shows as a ?1? after the first 30h command. future devices may support this feature. dq1: write to buffer abort dq1 indicates whether a write to buffer operation was aborted. under these conditions dq1 produces a ?1?. the system must issue the ?write to buffer abort reset? command sequence to return the device to reading array data. table 5. write operation status status dq7 (note 2) dq6 dq5 (note 1) dq3 dq2 (note 2) dq1 ry/by# embedded program algorithm dq7# toggle 0 n/a no toggle 0 0 standard mode embedded erase algorithm 0 toggle 0 1 toggle n/a 0 program suspended sector invalid (not allowed) 1 program suspend mode program suspend read non-program suspended sector data 1 erase suspended sector 1 no toggle 0 n/a toggle n/a 1 erase suspend read non-erase suspended sector data 0 erase suspend mode erase suspend program (embedded program) dq7# toggle 0 n/a n/a n/a 0 busy(note 3) dq7# toggle 0 n/a n/a 0 0 write to buffer abort(note 4) dq7# toggle 0 n/a n/a 1 0 notes 1. dq5 switches to 1 when an embedded program, embedded erase, or write-to-buffer operation has exceeded the maximum timing limits. 2. dq7 and dq2 require a valid address when reading status information. refer to the appropriate subsection for further details. 3. the data# polling algorithm should be used to monitor the last loaded write-buffer address location. 4. dq1 switches to 1 when the device has aborted the write-to-buffer operation writing commands/command sequences during a write operation, the system must drive ce# and we# to vil and oe# to vih when providing an address, command, and data. addresses are latched on the last falling edge of we# or ce#, while data is latched on the 1st rising edge of we# or ce#. an erase operation can erase one sector or the

(with the exception of ry/by#.) secured silicon sector flash memory region the secured silicon sector provides an extra flash memory region. the secured silicon sector is 128 words in length and all secured s ilicon reads outside of the 128-wo rd address range returns invalid data. the secure d silicon sector indicator bit, dq7, (at autos elect address 03h) is used to indicate whether or not the secured silicon sector is locked when shipped from the factory. please note the following general conditions: ? on power-up, or following a hard ware reset, the device reverts to sending commands to the normal address space. ? reads outside of sector sa0 return memory array data. ? sector sa0 is remapped from memory array to secured silicon sector array. ? once the secured silicon sector entry command is issued, the secured silicon sector exit command must be issued to exit secured silicon sector mode. ? the secured silicon sector is no t accessible when the device is executing an embedded program or embedded erase algorithm. ? when sector sa0 is suspe nded, if system enters secured silicon sector mode , the secured silicon sector region cannot be read. if the system suspends the flash in other sectors except sa0, secured silicon sector region can be read normally. ? the acc function is not available when the secured silicon sector is enabled.
