256Mb: 3V Embedded Parallel NOR Flash
Program Operations
1. The ENHANCED BUFFERED PROGRAM ABORT RESET command must be issued to return
the device to read mode.
Notes:
2. When the block address is specified, all addresses in the selected block address space
must be issued starting from 00h. Furthermore, when loading the write buffer address
with data, data program addresses must be consecutive.
3. DQ7 must be checked since DQ5 and DQ7 may change simultaneously.
4. If this flowchart location is reached because DQ5 = 1, then the ENHANCED BUFFERED
PROGRAM command failed. If this flowchart location is reached because DQ1 = 1, then
the ENHANCED BUFFERED PROGRAM command aborted. In both cases, the appropriate
reset command must be issued to return the device to read mode: A RESET command if
the operation failed; an ENHANCED BUFFERED PROGRAM ABORT RESET command if the
operation aborted.
EXIT ENHANCED BUFFERED PROGRAM Command
The EXIT ENHANCED BUFFERED PROGRAM command requires two bus write cycles
and is used to return the device to read mode. Until this command is issued, only the
ENHANCED BUFFERED PROGRAM command can be issued, and all other commands
are ignored.
