Abstract
The present disclosure relates to integrated circuits having tamper detection and response devices and methods for manufacturing such integrated circuits. One integrated circuit having a tamper detection and response device includes at least one photovoltaic cell and at least one memory cell coupled to the at least one photovoltaic cell. When the at least one photovoltaic cell is exposed to radiation, the at least one photovoltaic cell generates a current that causes an alteration to a memory state of the at least one memory cell. Another integrated circuit having a tamper detection and response device includes at least one photovoltaic cell and a reactive material coupled to the at least one photovoltaic cell, wherein a current from the at least one photovoltaic cell triggers an exothermic reaction in the reactive material.
