Abstract
An aspect of the present disclosure is a semiconductor device including: a property-variable element, an electrical property thereof changes with application of a higher voltage than a predetermined voltage; a write control switch that switches between conductive and non-conductive states based on a first signal; a first circuit that outputs a write voltage based on a power source and a second signal, the electrical property of the element being changed due to the application of the higher voltage to the element when the write voltage is output from the first circuit and the switch is in the conductive state; wiring for applying the higher voltage to the element; a second circuit that detects noise at the power source; and a noise discharge switch that enables noise current to be discharged from the wiring when the second circuit detects noise at the power source.
