Blocks Lock-Down
The Lock-Down feature provides an additional lev-
el of protection. A Locked-down block cannot be
unlocked by a software command. Locked-Down
blocks can only be unlocked by setting the Write
Protect signal to Low for a minimum of 100ns.
Only locked blocks can be locked-down. The com-
mand has no affect on unlocked blocks.
Refer to Figure 24., Command Latch AC Wave-
forms for details on how to issue the command.
Block Lock Status
In Block Lock mode (PRL High) the Block Lock
Status of each block can be checked by issuing a
Read Block Lock Status command (see Table
10.).
The command consists of:
■
one bus cycle to give the command code
■
three bus cysles to give the block address
After this, a read cycle will then output the Block
Lock Status on the I/O pins on the falling edge of
Chip Enable or Read Enable, whichever occurs
last. Chip Enable or Read Enable do not need to
be toggled to update the status.
The Read Block Lock Status command will not be
accepted while the device is busy (RB Low).
The device will remain in Read Block Lock Status
mode until another command is issued.

Note: Three address cycles are required for 2,4 and 8 Gb devices. 1Gb devices only require two address cycles.
