Abstract
A semiconductor integrated circuit device has a combinational logic circuit including one or plural logic cells connected in series. At least one of the logic cells includes a standard cell which includes a MIS transistor, an input terminal to which an output signal from a previous stage is inputted as an input signal, and an output terminal. A first conductivity-type first MIS transistor which is provided between the output terminal of the standard cell and a first power supply voltage, the first MIS transistor including a control terminal to which a circuit control signal is inputted, and the first MIS transistor supplying the first power supply voltage to the output terminal of the standard cell based on the circuit control signal in order to bring the standard cell into an operation-stopped state. A second conductivity-type second MIS transistor cuts off a leakage current of the MIS transistor in the standard cell.
