Abstract
A data receiving circuit may include: a variable delay circuit suitable for generating a delayed strobe signal by delaying a strobe signal; a receiving circuit suitable for sampling data in synchronization with the delayed strobe signal; a phase shift circuit suitable for generating a shifted strobe signal by shifting a phase of the delayed strobe signal; a phase comparison circuit suitable for comparing phases of the data and the shifted strobe signal; and a delay adjusting circuit suitable for adjusting a delay value of the variable delay circuit in response to the phase comparison result of the phase comparison circuit.
