A semiconductor device includes a first pad suitable for receiving a first clock that is inputted from an exterior, a second pad suitable for receiving a second clock that is inputted from the exterior, a differential clock recognition unit suitable for recognizing between the first clock and the second clock as a positive clock of differential clocks and recognizing the other as a negative clock of the differential clocks in response to a mirror function signal which represents whether a mirror function is enabled or not, an output unit suitable for outputting an internal signal as an output signal in response to the differential clocks and controlling an output moment of the output signal in response to the mirror function signal and an output moment control signal, and a third pad suitable for supplying the output signal to the exterior. |
