ABSTRACT:
A semiconductor integrated circuit device comprises: a circuit block, a first MOS transistor, a first power line, a second power line, a third power line, and a drive circuit. The first MOS transistor is connected between the first and second power lines. The circuit block is connected between the second and third power lines. The drive circuit controls a voltage supplied to a gate of the first MOS transistor. The first MOS transistor is off in a standby state and on in an operation state. During a shift from the standby state to the operation state and a shift from the operation state to the standby state, the drive circuit changes the voltage supplied to the gate of the first MOS transistor at a first rate, and then, changes the voltage supplied to the gate of the first MOS transistor at a second rate faster than the first rate.
