ABSTRACT:
To provide an optically reconfigurable logic circuit in which a mount area of an optical circuit is reduced as much as possible and a high gate density is realized.In an optically reconfigurable logic circuit1provided with a plurality of configuration information input circuits6for converting an optical signal including logic circuit configuration information into an electric signal and holding and outputting this electric signal and a logic configuration variable circuit7for performing logic configuration on the basis of the logic circuit configuration information, the configuration information input circuits6holds the logic circuit configuration information as electric charge with use of a junction capacitance and a floating capacitance of a photoconductive device P. An inter-terminal voltage of the photoconductive device P is converted into binary data by a binary circuit and output as a circuit configuration signal. Then, the logic configuration variable circuit7is configured to execute a logic arithmetic processing before the inter-terminal voltage of the photoconductive device P drops to be equal to or lower than a logic threshold of the binary circuit due to a leak current.
