Lock Register
As shipped from the factory, all devices default to the persistent mode when power is applied, and
all sectors are unprotected, unless otherwise chosen through the DYB ordering option. The device
programmer or host system must then choose which sector protection method to use. Program-
ming (setting to “0”) any one of the following two one-time programmable, non-volatile bits locks
the part permanently in that mode:
Lock Register Persistent Protection Mode Lock Bit (DQ1)
Lock Register Password Protection Mode Lock Bit (DQ2)
Table 6. Lock Register
Notes
1. If the password mode is chosen, the password must be programmed before setting the cor-
responding lock register bit.
2. After the Lock Register Bits Command Set Entry command sequence is written, reads and
writes for Bank 0 are disabled, while reads from other banks are allowed until exiting this
mode.
3. If both lock bits are selected to be programmed (to zeros) at the same time, the operation
aborts.
4. Once the Password Mode Lock Bit is programmed, the Persistent Mode Lock Bit is permanently
disabled, and no changes to the protection scheme are allowed. Similarly, if the Persistent
Mode Lock Bit is programmed, the Password Mode is permanently disabled.
After selecting a sector protection method, each sector can operate in any of the following three
states:
1. Constantly locked. The selected sectors are protected and can not be reprogrammed unless
PPB lock bit is cleared via a password, hardware reset, or power cycle.
2. Dynamically locked. The selected sectors are protected and can be altered via software com-
mands.
3. Unlocked. The sectors are unprotected and can be erased and/or programmed.
Persistent Protection Bits
The Persistent Protection Bits are unique and nonvolatile for each sector and have the same en-
durances as the Flash memory. Preprogramming and verification prior to erasure are handled by
the device, and therefore do not require system monitoring.
Notes
1. Each PPB is individually programmed and all are erased in parallel.
2. While programming PPB for a sector, array data can be read from any other bank, except Bank
0 (used for Data# Polling) and the bank in which sector PPB is being programmed.
3. Entry command disables reads and writes for the bank selected.
4. Reads within that bank return the PPB status for that sector.
5. Reads from other banks are allowed while writes are not allowed.
