256Mb: 3V Embedded Parallel NOR Flash
Program Operations
tions or the incorrect sequence of bus WRITE cycles will abort the WRITE TO BUFFER
PROGRAM command.
The status register bits DQ1, DQ5, DQ6, DQ7 can be used to monitor the device status
during a WRITE TO BUFFER PROGRAM operation.
An external 12V supply can be used to improve programming efficiency.
When reprogramming data in a portion of memory already programmed (changing
programmed data from '0' to '1') operation failure can be detected by a logical OR be-
tween the previous and the current value.
