Abstract

Demand for a large-gate-count robust VLSI chip that is usable in a radiation-rich space environment is increasing daily. 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. However, the ORGA has only an unallowable failure mode, which is a turn-off failure mode of a laser array. This paper therefore presents a proposal of a recovery method for a turn-off failure mode of a laser array on an ORGA and presents its demonstration results.
