Storage device

Abstract

Data retained in a volatile storage unit can be stored in a nonvolatile storage unit on the basis of voltage drive. The storage device includes a volatile storage unit that complementarily retains data, a voltage controlled magnetoresistive effect element that retains the data complementarily retained in the volatile storage unit, a first variable resistance element that is connected between the volatile storage unit and the voltage controlled magnetoresistive effect element and has a variable resistance between the volatile storage unit and the voltage controlled magnetoresistive effect element, and a second variable resistance element that is connected between the volatile storage unit and the voltage controlled magnetoresistive effect element with an inverter interposed therebetween and has a variable resistance between the volatile storage unit and the voltage controlled magnetoresistive effect element.
