Abstract
A third gate circuit which is controlled by a clock signal and operates upon the detection of change of a signal on a critical path driven by a first gate circuit and transmits a signal provided by the first gate circuit to a second gate circuit is connected to the critical path at a position near the second gate circuit. The third gate circuits operates upon the detection of change of the signal to increase the speed of change of the signal. Thus, the ratio of a delay time attributable to wiring resistance in the critical path of a semiconductor integrated circuit is reduced, the speed of the critical path is increased and the operating frequency of the semiconductor integrated circuit can be improved.
