Abstract :
Demand is increasing daily for a robust VLSI chip that is useful for operating under a radiation-rich space environment, such as spacecraft, space satellites, and space stations. Optically reconfigurable gate arrays (ORGAs) have been developed to realize a large virtual gate count that is much larger than those of current VLSI chips by exploiting the large storage capacity of a holographic memory. The ORGA architecture is extremely robust for many failure modes caused by high-energy charged particles. This paper presents a robust 16-laser array for an optically reconfigurable gate array and its demonstration results.
