摘要： A shift circuit of a semiconductor device reduces the power consumption of the semiconductor device. The shift circuit comprises a plurality of shifters and a plurality of clock controllers. The plurality of shifters shifts an input signal in sequence in response to a clock. The plurality of clock each supply the clock to a corresponding shifter before an input of the corresponding shifter is activated and stop the supply of the clock to the corresponding shifter when an output of the corresponding shifter is activated.
