PROGRAM RESUME Command
*Advanced information. Subject to change without notice.
The PROGRAM RESUME (30h) command must be issued to exit a program suspend mode and resume a
PROGRAM operation. The controller can use DQ7 or DQ6 data polling bits to determine the status of the
PROGRAM operation. After a PROGRAM RESUME command is issued, subsequent PROGRAM RESUME
commands are ignored. Another PROGRAM SUSPEND command can be issued after the device has
resumed programming.
Erase Operations
CHIP ERASE Command
The CHIP ERASE (80/10h) command erases the entire chip. Six bus WRITE operations are required to issue
the command and start the program/erase controller.
Protected blocks are not erased. If all blocks are protected, the data remains unchanged. No error is reported
when protected blocks are not erased.
During the CHIP ERASE operation, the device ignores all other commands, including ERASE SUSPEND. It
is not possible to abort the operation. All bus READ operations during CHIP ERASE output the data polling
register on the data I/Os.
UNLOCK BYPASS CHIP ERASE Command
When the device is in unlock bypass mode, the UNLOCK BYPASS CHIP ERASE (80/10h) command can be
used to erase all memory blocks at one time. The command requires only two bus WRITE operations instead
of six using the standard CHIP ERASE command. The final bus WRITE operation starts the program/erase
controller.
BLOCK ERASE Command
The BLOCK ERASE (80/30h) command erases a list of one or more blocks. It sets all bits in the selected,
unprotected blocks to 1. All previous, selected, unprotected blocks data in the selected blocks is lost.
UNLOCK BYPASS BLOCK ERASE Command
When the device is in unlock bypass mode, the UNLOCK BYPASS BLOCK ERASE (80/30h) command can
be used to erase one or more memory blocks at a time. The command requires two bus WRITE operations
instead of six using the standard BLOCK ERASE command. The final bus WRITE operation latches the address
of the block and starts the program/erase controller.
