Recently, optically reconfigurable gate arrays (ORGAs) that can realize dynamic reconfiguration have been developed. The ORGAs consists of a holographic memory, a laser array, and a gate array VLSI. ORGAs are new type VLSIs, the gate arrays of which are optically reconfigured using diffraction patterns from a holographic memory that is addressed using a laser diode array. However, conventional ORGAs have one important shortcoming. They cannot be reprogrammed after fabrication. Therefore, to improve that shortcoming, we have been developing a programmable optically reconfigurable gate array architecture. So, this paper presents the demonstration of a programmable 9-contexts optically reconfigurable gate arrays and its writer.
