    摘要： There is provided a semiconductor integrated circuit, a logic operation circuit and a flip flop capable of operating at a high speed and having a leak electric current reduced.
    In a semiconductor integrated circuit according to the present invention, only a gate circuit on a critical path is constituted by an MT gate cell obtained by combining transistors having a low threshold voltage with transistors having a high threshold voltage, and any other gate circuit is constituted by a transistor having a high threshold voltage. Consequently, the gate circuit on the critical path can be operated at a high speed, and the overall leak electric current can be suppressed, thereby reducing the consumption power.

    摘要： A combination circuit (11) is switched between an active state where power is supplied thereto in response to a control signal and an inactive state where power thereto is interrupted. A flip-flop circuit (13) connected to an input terminal of the combination circuit stores an output signal of the combination circuit in response to a clock signal. The combination circuit (11) is set to an operative state by the control signal immediately before the flip-flop circuit (13) operates in response to the clock signal.
