A semiconductor device includes a buffer suitable for receiving an input signal, a clock buffer suitable for receiving a clock, a delay locked loop (DLL) suitable for delaying the clock to generate a delay locked clock, a code generation unit suitable for generating a digital code corresponding to 1/N of the clock cycle where N is an integer equal to or more than two, a delay unit suitable for delaying the clock corrected by the DLL by a value corresponding to the digital code to output a delayed clock, and a strobing unit suitable for strobing the input signal using the delayed clock.
