Abstract

A semiconductor device includes a first potential supply line for supplying a first potential, a second potential supply line for supplying a second potential lower than the first potential, a functional circuit, and at least one of a first switch disposed between the first potential supply line and the functional circuit and a second switch disposed between the second potential supply line and the functional circuit. The first switch and the second switch are negative capacitance FET.
