Abstract

The disclosed technology generally relates to integrated circuit devices with wear out monitoring. An integrated circuit device includes a core circuit and a wear-out monitor device. The wear-out monitor device configured to adjust an indication of wear out of the core circuit regardless of whether the core circuit is activated The integrated circuit further includes a sensing circuit coupled to the wear-out monitor device and configured to detect an electrical property of the wear-out monitor device that is indicative of a wear-out level of the core-circuit.
