Customer-lockable Extended Memory Block
A device where the Extended Memory Block is customer-lockable is delivered with the DQ7
bit set to ‘0’ and the Extended Memory Block unprotected. It is up to the customer to
program and protect the Extended Memory Block but care must be taken because the
protection of the Extended Memory Block is not reversible.
If the device has not been shipped with the Extended Memory Block pre-protected, the
block can be protected by setting the Extended Memory Block Protection bit, DQ0, to ‘0’.
However, this bit can only be programmed once; and once it is protected the Extended
Memory Block cannot be unprotected.
Once the Extended Memory Block is programmed, the Exit Extended Memory Block
command must be issued to exit the Extended Memory Block mode and return the device to
Read mode.
