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.

Abstract: The detection circuit has a non-volatile electrically programmable storage circuit (116) and a programming circuit (110) which gradually modifies the programming of the storage circuit with each use. A measuring circuit (120) monitors the storage circuit, and issues an alarm signal when a set number of uses is exceeded.
