Abstract:
The subject disclosure relates to techniques for providing semiconductor chip security using piezoelectricity. According to an embodiment, an apparatus is provided that comprises an integrated circuit chip comprising a pass transistor that electrically connects two or more electrical components of the integrated circuit chip. The apparatus further comprises a piezoelectric element electrically connected to a gate electrode of the pass transistor; and a packaging component that is physically connected to the piezoelectric element and applies a mechanical force to the piezoelectric element, wherein the piezoelectric element generates and provides a voltage to the gate electrode as a result of the mechanical force, thereby causing the pass transistor to be in an on-state. In one implementation, the two or more electrical components comprise a circuit and a power source. In another implementation, the two or more electrical components comprise two circuits.
