ABSTRACT:
A circuit to detect the use of an element of an integrated circuit may include a non-volatile electrically programmable storage circuit and a programming circuit. The programming circuit may be used to partially program the storage circuit and gradually modify its programming level as the element is used so that the level represents the number of uses of the element.
