Abstract: A semiconductor integrated circuit includes a first control part included in a first region in which a first operation speed is permitted, a second control part included in a second region in which power supply is cut off in a power saving mode and in which an operation at a speed higher than the first operation speed is required, a functional part having a specific function, and a selection part selecting either a first path connecting the first control part and the functional part or a second path connecting the second control part and the functional part in response to a control signal.
