Abstract
A semiconductor device comprises: reconfigurable logic circuit that includes plurality of resistance change elements; logical configuration of the reconfigurable logic circuit being decided depending on whether each of plurality of resistance change elements is in first resistance state or in second resistance state whose resistance value is lower than resistance value of first resistance state; resistance value monitor circuit that includes resistance change element pre-programmed to the first resistance state; the resistance value monitor circuit detecting whether or not pre-programmed resistance change element retains the first resistance state; and controller that, in case it is detected that resistance change element provided in resistance value monitor circuit doe not retain first resistance state, applies voltage used in programming from second resistance state to first resistance state to resistance change element retaining first resistance states, out of plurality of resistance change elements provided in reconfigurable logic circuit.
