Abstract: A method of operating a non-volatile memory includes; during power-on, reading control information from an information block and lock information from an additional information block, then upon determining that a secure block should be locked, generating a lock enable signal that inhibits access to data stored in the secure block, and a read-only enable signal that prevents change in the data stored in the additional information block.
