ABSTRACT:
A method and circuit for preventing the overprogramming of a memory cell. A fuse circuit is operable to be blown. A combinational logic circuit receives a signal from the fuse circuit, indicating whether or not the fuse has been blown, and controls the programming of the memory cell. The programming of the memory cell is prevented if the fuse circuit has been blown.
