A state machine with a dynamic clock gating function according to the invention is disclosed. In the state machine, a gating clock control logic is used to gate a clock signal input to flip-flops which do not need a clock sample input. Accordingly, the total capacitance of capacitors which are charged/discharged following the state transition of a clock signal is greatly reduced, thereby decreasing the power consumption of the state machine.
