Abstract
Disclosed is a nonvolatile memory having lockable cell array. The memory includes a lockable cell array formed of a plurality of lockable cell transistors and lockable word lines coupled to gates of the lockable cell transistors; and a lockable pass transistor array formed of a plurality of lockable pass transistors connecting the lockable word lines to a plurality of selection signals. The lockable word lines are coupled to boosting elements which are in response to capacitive coupling in a bulk during an unlock operation.
