Abstract

The disclosed technology generally relates to integrated circuit devices with wear out monitoring capability. An integrated circuit device includes a wear-out monitor device configured to record an indication of wear-out of a core circuit separated from the wear-out monitor device, wherein the indication is associated with localized diffusion of a diffusant within the wear-out monitor device in response to a wear-out stress that causes the wear-out of the core circuit.
