Abstract
An electronic chip including an integrated circuit arranged a face of a substrate, and a protection device arranged partially facing the integrated circuit is provided. The protection device includes a capacitor having a first electrode and a second electrode between which a layer of phase change material is disposed changing locally from a first resistive state to a second resistive state different from the first state by penetration of a beam. The first state is an amorphous state wherein the capacitor has a first capacitance and/or a first resistance and the second state is a crystalline state wherein the capacitor has a second capacitance and/or a second resistance different from the first capacitance and first resistance. The protection device is electrically connected to the integrated circuit by at least one of the first or second electrodes so that the integrated circuit measures the resistance and/or capacitance of the capacitor.
