13.1.1
Lock
All blocks default to locked (state [x01]) after initial power-up or reset. Locked blocks are fully
protected from alteration. Attempted program or erase operations to a locked block will return an
error in SR[1]. Unlocked blocks can be locked by using the Lock Block command sequence.
Similarly, a locked block’s status can be changed to unlocked or lock-down using the appropriate
software commands.
13.1.2
Unlock
Unlocked blocks (states [x00] and [110]) can be programmed or erased. All unlocked blocks return
to the locked state when the device is reset or powered-down. An unlocked block’s status can be
changed to the locked or locked-down state using the appropriate software commands. A locked
block can be unlocked by writing the Unlock Block command sequence if the block is not locked-
down.
13.1.3
Lock-Down
Locked-down blocks (state [011]) offer the user an additional level of write protection beyond that
of a regular locked block. A block that is locked-down cannot have it’s state changed by software if
WP# is asserted. A locked or unlocked block can be locked-down by writing the Lock-Down Block
command sequence. If a block was set to locked-down, then later changed to unlocked, a Lock-

Notes:
1. [a,b,c] represents [WP#, D1, D0]. X = Don’t Care.
2. D1 indicates block Lock-down status. D1 = ‘0’, Lock-down has not been issued to
this block. D1 = ‘1’, Lock-down has been issued to this block.
3. D0 indicates block lock status. D0 = ‘0’, block is unlocked. D0 = ‘1’, block is locked.
4. Locked-down = Hardware + Software locked.
5. [011] states should be tracked by system software to determine difference between
Hardware Locked and Locked-Down states.
