Abstract
In a programmable logic integrated circuit, providing a spare circuit in preparation for the occurrence of a defective element results in a redundant circuit configuration. A programmable logic integrated circuit according to the present invention has: a plurality of logic blocks; a switch block for switching the connections between row and column wires by nonvolatile switch elements for switching; and a shifter block for connecting an input/output wire to said switch block. The shifter block includes a redundant wire and is equipped with nonvolatile switch elements for shifting that control the connections of the wires constituting said redundant wire and said row wires.
