Recently, fast reconfigurable devices, optically reconfigurable gate arrays (ORGAs) have been develped. The ORGA consits of a holographic memory, a laser array, and a gate array VLSI. However, conventional ORGAs have a demerit that they can not be reprogrammed after its fabrication. Therefore, in order to improve the demerit, this paper presents the architecture of a programmable ORGA with four configuration contexts.
