Block Erase
The device supports Random Data Input within a page. The column address of next data, which will be
entered, may be changed to the address which follows the Random Data Input command (85h). Random
Data Input may be operated multiple times regardless of how many times it is done in a page.
The Program Confirm command (10h) initiates the re-programming process. The internal write state
controller automatically executes the algorithms and controls timings necessary for program and verify,
thereby freeing the system controller for other tasks. Once the program process starts, the Read Status
Register command may be issued to read the Status Register. The system controller can detect the
completion of a program cycle by monitoring the R/B# output, or the Status bit (I/O6) of the Status Register.
Only the Read Status command and Reset command are valid when programming is in progress. When the
Page Program is complete, the Write Status Bit (I/O0) may be checked. The internal write verify detects only
errors for 1’s that are not successfully programmed to 0’s. The command register remains in Read Status
command mode until another valid command is written to the command register.
The Page Reprogram must be issued in the same plane as the Page Program that failed. In order to program
the data to a different plane, use the Page Program operation instead. The Multiplane Page Reprogram can
reprogram two pages in parallel, one per plane. The Multiplane Page Reprogram operation is performed after
a failed Multiplane Page Program operation. The command sequence is very similar to
on page
If a Page Reprogram operation is interrupted by hardware reset, power failure or other means, the host must
ensure that the interrupted page is not used for further reading or programming operations until the next
uninterrupted block erase is complete.
The Block Erase operation is done on a block basis. Block address loading is accomplished in three cycles
(two cycles for S34ML01G1) initiated by an Erase Setup command (60h). Only the block address bits are
valid while the page address bits are ignored.
The Erase Confirm command (D0h) following the block address loading initiates the internal erasing process.
This two-step sequence of setup followed by the execution command ensures that memory contents are not
accidentally erased due to external noise conditions.
At the rising edge of WE# after the erase confirm command input, the internal write controller handles erase
and erase verify. Once the erase process starts, the Read Status Register commands (70h or 78h) may be
issued to read the Status Register.
The system controller can detect the completion of an erase by monitoring the R/B# output, or the Status bit
(I/O6) of the Status Register. Only the Read Status commands (70h or 78h) and Reset command are valid
while erasing is in progress. When the erase operation is completed, the Write Status Bit (I/O0) may be
checked.
If a Block Erase operation is interrupted by hardware reset, power failure or other means, the host must
ensure that the interrupted block is erased under continuous power conditions before that block can be
trusted for further programming and reading operations.
49, except that it requires the Page Reprogram Command (8Bh) instead of 80h and 81h.
