SEMICONDUCTOR CIRCUIT HAVING FUNCTION OF POWER GATING AND SEMICONDUCTOR DEVICE INCLUDING THE SAME

摘要

PURPOSE: A power gating semiconductor circuit and a semiconductor device including the same are provided to reduce a gate leakage current by applying a low gate voltage to a gate of a transistor which is turned on. CONSTITUTION: A logic unit(200) maintains an output signal with a standby logic level in a standby mode. A power gating unit(100) applies a power voltage to the logic unit in a driving mode based on a standby mode enable signal. The power gating unit partially applies a standby mode power voltage which is lower than the power voltage in the standby mode to a logic level maintaining area of the logic unit which is activated to maintain a standby logic level.
