Abstract
A secure electronic chip including a plurality of biased semiconductor wells and a well biasing current detection circuit. Each of the wells includes a transistor and a bias contact electrically isolated from the transistor. The detection circuit is electrically coupled to each bias contact and is configured to detect a bias current passing through the bias contact that is indicative of an attempt to tamper with the electronic chip.
