SR[5]. If a command sequence error occurs during an erase suspend, SR[4] and SR[5] remains set,
even after the erase operation is resumed. Unless the Status Register is cleared using the Clear
Status Register command before resuming the erase operation, possible erase errors may be
masked by the command sequence error.
If a block is locked or locked-down during an erase suspend of the
same
block, the lock status bits
change immediately. However, the erase operation completes when it is resumed. Block lock
operations cannot occur during a program suspend. See
Appendix A, “Write State Machine” on
page 78
, which shows valid commands during an erase suspend.
13.2
Selectable One-Time Programmable Blocks
Any of four pre-defined areas from the main array (the four 32 KB parameter blocks together as
one and the three adjacent 128 KB main blocks) can be configured as One-Time Programmable
(OTP) so further program and erase operations are not allowed. This option is available for top or
bottom parameter devices.
Please see your local Intel representative for details about the Selectable OTP implementation.

Note:

the number of 256-Mbit dies in the stack and the placement of the parameter blocks.
