The first input circuit detects an input signal to output a first output signal having the same phase as the input signal. The second input circuit is configured to detect a first strobe signal to output a second output signal. The third input circuit is configured to detect a second strobe signal as a reversed signal of the first strobe signal to output a third output signal. A data latch circuit includes a first latch circuit and a second latch circuit. It is configured to latch the first output signal in either one of the first latch circuit or the second latch circuit according to the first output signal, the second output signal and the third output signal. It also allows the other one of the first latch circuit or the second latch circuit to input the first output signal thereto.
