See full text

Provided is a power gating control circuit for stably controlling data restoring. The power gating control circuit includes a retention circuit and a non-retention circuit. The retention circuit includes a first flip-flop, which stores or restores data of the first flip-flop in a power gating mode. The non-retention circuit includes a second flip-flop and a third flip-flop. The power gating control circuit performs initialization of data of the second flip-flop and the third flip-flop in the power gating mode, and an initialization operation of the non-retention circuit is controlled to be performed before data of the retention circuit is restored.
