Optically reconfigurable gate arrays (ORGAs) have been developed as a type of dynamically reconfigurable gate array that can achieve a high-speed reconfiguration and numerous reconfiguration contexts. An ORGA consists of laser array, holographic memory, and an optically reconfigurable gate array VLSI. An ORGA has a radiation tolerance. However, a previous polymer-dispersed liquid crystal holographic memory cannot work at a high-temperature condition. So, we have fabricated a temperature-tolerant holographic memory using a holographic polymer-dispersed liquid crystal. This paper presents a new optically reconfigurable gate array using the temperature-tolerant holographic memory.
