Abstract:
Systems and methods to ensure correct operation of a semiconductor chip in the presence of ionizing radiation is disclosed. The system includes a semiconductor chip, a first radiation detection array incorporated in the semiconductor chip, and at least one additional radiation detection array incorporated in the semiconductor chip. a processor determines a region of the semiconductor chip affected by an incident radiation particle by analyzing a trajectory of the radiation particle determined from locations of sensors hit by the radiation particle in the first radiation detection array and the at least one additional radiation detection array. The processor determines whether corrective action is needed based on the region of the semiconductor chip affected by the incident radiation particle.
