Summary: | The present invention relates to a semiconductor device and an operating method thereof. The semiconductor device includes: a power gating unit which includes a synchronous reset flip-flop unit; a retention unit including a retention flip-flop unit; a clock management unit which provides an operation clock for the retention unit and the power gating unit; and a power management unit which transmits power gating control signals to the power gating unit, retention unit, and clock management unit. The power gating circuit is activated to signal entry to a power reduction mode. The retention circuit retains states of the semiconductor device. Upon exit from the power reduction mode, the power management circuit is configured to complete a reset operation of the power gating circuit before signaling the retention circuit to cancel a retention state and restore the states of the semiconductor device.
