Abstract
A semiconductor apparatus may include a logic circuit, a power gating circuit and a power gating control system. The logic circuit may operate by receiving a first power supply voltage and a second power supply voltage, and may retain an output signal at a predetermined logic value during a standby operation of the semiconductor apparatus. The power gating circuit may apply the first power supply voltage and the second power supply voltage to the logic circuit when a gating control signal is in an enabled state. The power gating control system may test whether the output signal of the logic circuit retains the predetermined logic value when the power gating circuit is turned off, and may generate the gating control signal based on a test result and an operation mode of the semiconductor apparatus.
