ABSTRACT:
A security memory device includes a memory cell array that stores a plurality of contents, including a mine, which is stored as a portion of the plurality of contents. The mine is triggered when it is accessed, typically such that the mine erases the memory contents. Also, control logic is included that controls access to the plurality of contents. In one aspect, the memory cell array can include a protected-cell zone and a free-cell zone. In this aspect, the security memory device can further include a lock that provides protection for contents stored in the protected-cell zone from access and a key that is capable of unlocking the lock.
