Abstract:
1. A semiconductor integrated circuit device comprising: a plurality of circuit elements functioning as part of a configured circuit; a plurality of connection elements each of which becomes a conductive state or a nonconductive state to connect or disconnect at least part of the circuit elements of said plurality of circuit elements to and from each other; interconnects for supplying control signals for placing said plurality of connection elements in said conductive state or nonconductive state; and a plurality of circuit selection switching elements which become a conductive state or a nonconductive state in response to a circuit configuration instruction signal in accordance with the desired circuit to be configured and apply said control signals to said interconnects in the conductive state, wherein said connection elements include magnetoresistance effect elements which enter a conductive state or nonconductive state in accordance with application of a magnetic field and wherein said device maintains a continuous conductive state by application of a continuous magnetic field generated by continuous control signals supplied to said interconnects to said magnetoresistance effect elements.
