Abstract:
An apparatus is described that includes a plurality of circuits each designed to exhibit a unique signature code that is determined from manufacturing tolerances associated with a manufacturing process used to manufacture the circuits. The apparatus also includes error circuitry to determine an error has arisen based on a change in signature codes from the plurality of circuits.
