ABSTRACT:
In one embodiment, the present invention relates to a particular configuration of a non-volatile counter, which significantly reduces the amount of area required for implementation in an integrated circuit and improves its reliability of operation. This is accomplished by (1) replacing the volatile binary counter with a volatile counter coded for more equal distribution the changes in logic state over the entire counter, (2) replacing the non-volatile latch circuit with a single non-volatile memory element, and (3) developing testing techniques for complete and efficient testing of the critical non-volatile memory elements.
