ABSTRACT:
A flash memory device including a first memory array, block locking circuitry, and control circuitry. The memory array includes a plurality of memory blocks each having a memory cell. The block locking circuitry includes a plurality of block lock-bits and a master lock-bit. Each block lock-bit corresponds to one of the plurality of memory blocks and indicates whether the corresponding memory block is locked. The master lock-bit indicates whether the plurality of block lock-bits are locked. The control circuitry is configured to receive a passcode that causes the control circuitry to override the master lock-bit. The control circuitry may also be configured to receive a passcode that causes the control circuitry to override one of the block lock-bits.
