It is possible to detect program operation fails when changing programmed data from ‘0’ to
‘1’, that is when reprogramming data in a portion of memory already programmed. The
resulting data will be the logical OR between the previous and the current value.
See
a suggested flowchart on using the Enhanced Buffered Program command.
Buffered Program Abort Reset command
A Buffered Program Abort Reset command must be issued to abort the write to buffer
program and enhanced buffered program operation and reset the device in read mode.
The write to buffer and enhanced buffered programming sequence can be aborted in the
following ways:
The abort condition is indicated by DQ1 = 1, DQ7 = DQ7 (for the last address location
loaded), DQ6 = toggle, and DQ5 = 0 (all of which are status register bits). A Buffered
Program Abort and Reset command sequence must be written to reset the device for the
next operation. Note that the full 3-cycle Buffered Program Abort and Reset command
sequence is required when using write to buffer and enhanced buffered programming
features in unlock bypass mode.
Enhanced Buffered Program commands are available for x 16 mode only.
Appendix D
Load a value that is greater than the page buffer size during the number of locations to
program step in the Write to Buffer Program command
Write to an address in a block 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
Write data other than the Confirm command after the specified number of data load
cycles
Load address/data pairs in an incorrect sequence during the enhanced buffered
program.
