Semiconductor apparatus includes first power supply line and second power supply line, first sub power supply line, first switch circuit, first logic circuit and first control circuit. First switch circuit is disposed between first power supply line and first sub power supply line, and controlled based on first signal. First logic circuit is disposed between first sub power supply line and second power supply line and comprises first input node and second input node receiving second signal and third signal respectively, and output node. First logic circuit outputs an active voltage associated with a logical level of second signal to output node in active state, and outputs a standby voltage associated with a voltage of second power supply line to output node regardless of the logical level of second signal in non-active state. First control circuit generates third signal based on first signal and fourth signal independent of first signal, and letting first logic circuit transit from non-active state to active state by providing third signal to second input node of first logic circuit.
