WP# Lock-Down Control
The Write Protect signal, WP#, adds an additional layer of block security. WP# only
affects blocks that once had the Lock-Down command written to them. After the lock-
down status bit is set for a block, asserting WP# forces that block into the lock-down
state [011] and prevents it from being unlocked. After WP# is deasserted, the block’s
state reverts to locked [111] and software commands can then unlock the block (for
erase or program operations) and subsequently re-lock it. Only device reset or power-
down can clear the lock-down status bit and render WP# ineffective.
Protection Register
The Numonyx Wireless Flash Memory (W18) includes a 128-bit Protection Register. This
protection register is used to increase system security and for identification purposes.
The protection register value can match the flash component to the system’s CPU or
ASIC to prevent device substitution.
The lower 64 bits within the protection register are programmed by Numonyx with a
unique number in each flash device. The upper 64 OTP bits within the protection
register are left for the customer to program. Once programmed, the customer
segment can be locked to prevent further programming.
The individual bits of the user segment of the protection register are OTP, not the
register in total. The user may program each OTP bit individually, one at a time, if
desired. After the protection register is locked, however, the entire user segment is
locked and no more user bits can be programmed.
