Abstract
A device performing a power gating operation includes a switch control signal generation circuit and a power gating circuit. The switch control signal generation circuit controls an operation that generates a first switch control signal and a second switch control signal from a mode signal based on a comparison result of a first power source voltage and a second power source voltage until a mode register set operation is performed after a power-up period ends. The power gating circuit drives a power source voltage to the first power source voltage or the second power source voltage based on the first switch control signal and the second switch control signal.
