Abstract
A semiconductor device comprises a control unit, a semiconductor memory, a reference capacitance unit, a determination capacitance unit, a calibration circuit configured to supply a selection signal to the reference capacitance unit to selectively connect capacitors to differing potentials, and a determination circuit configured to charge a capacitance of the reference capacitance unit, to charge a capacitance of the determination capacitance unit, and to attain a comparison result by comparing the differing potentials. The control unit is configured to control rewriting of the semiconductor memory on the basis of a determination result of the determination circuit.
