To provide a reconfiguration controller of an optically reconfigurable gate array for correctly and reliably writing various types of logical operation circuits of an optically reconfigurable gate array and performing high-speed logical operation by quickly starting up the circuits. [MEANS FOR SOLVING PROBLEMS] A reconfiguration controller comprises a laser array (1) for producing a laser beam (1a) to serve as a reproducing beam and applying the laser beam (1a), a hologram memory (2) for outputting an optical pattern (2a) when receiving the laser beam (1a) according to pre-stored recording information and outputting a control signal light (2b) relating to optical reconfiguration by the optical pattern (2a), an optically reconfigurable gate array (3) for reconfiguring arrayed logical operation cells into various logical operation circuits according to the outputted optical pattern (2a), and outputting an optical control signal (S3) from the control signal light (2b), and a reproduction light application control means (4) for controlling the application of the laser beam (1a) emitted from the laser array (1) according to the optical control signal. Therefore, optical pattern application can be performed according to the optical control signal at a reconfiguration time adapted to any of various logical operation circuits sequentially reconfigured by the optically reconfigurable gate array. Consequently, correct and reliable write of any one of various types of logical operation circuits can be performed without any write error, and such various types of logical operation circuits can perform logical operation sequentially at high speed.
