A shared delay circuit of a semiconductor device can share a plurality of delay elements having the same function by integrating the delay elements. The shared delay circuit includes an input signal conversion unit for converting a plurality of input signals into a plurality of pulse signals, a delay unit for delaying the pulse signals outputted from the input signal conversion unit for a predetermined time to output the delayed pulse signal, and a switch and output control unit for receiving the pulse signals outputted from the input signal conversion unit and the delayed pulse signals delayed for the predetermined time through the delay unit, and outputting the delayed pulse signals in the same form as the input signals inputted to the input signal conversion unit. According to the shared delay circuit, the repeated arrangement of circuits having the same function can be avoided by sharing the delay circuits in the semiconductor device and thus the installation area of the delay circuits can be reduced.
