By default at power-on, if LOCK is HIGH, all the blocks are locked and protected from
PROGRAM and ERASE operations. If portions of the device are unlocked using the UN-
LOCK (23h) command, they can be locked again using the LOCK (2Ah) command. The
LOCK command locks all of the blocks in the device. Locked blocks are write-protected
from PROGRAM and ERASE operations.
To lock all of the blocks in the device, issue the LOCK (2Ah) command.
When a PROGRAM or ERASE operation is issued to a locked block, R/B# goes LOW for
t
mand reports bit 7 as 0, indicating that the block is protected.
The LOCK (2Ah) command is disabled if LOCK is LOW at power-on or if the device is
locked tight.
