A semiconductor device comprising:
- an input receiver circuit activated by a strobe signal to generate an output signal by comparing a potential of an input signal with a reference potential;
- and
- a noise canceller cancelling noise superimposed on the reference potential due to a change in the strobe signal,
- wherein the noise canceller comprises:
- an opposite-phase signal generation circuit generating an opposite-phase signal of the strobe signal;
- a first replica transistor controlled by the reference potential;
- and
- a second replica transistor connected to the first replica transistor and controlled by the opposite-phase signal.

A semiconductor device comprising:
- an input circuit comparing an input signal supplied via an input signal line with a reference voltage supplied via a reference voltage supply line to output an output signal, an operation timing of the input circuit being controlled by a control signal supplied via a control signal line;
- and
- a noise cancellation circuit connected between the control signal line and the reference voltage supply line,
- wherein the noise cancellation circuit comprises an opposite-phase signal generation circuit generating an opposite-phase signal of the control signal, a first replica transistor controlled by the reference potential, and a second replica transistor connected to the first replica transistor and controlled by the opposite-phase signal, and
- wherein any circuit that cancels noise is not connected between the control signal line and the input signal line.
