Abstract
Provided are a digital phase interpolator, a clock signal generator, and a volatile memory device including the clock signal generator. The clock signal generator includes an internal signal generator configured to generate a first internal signal and a second internal signal, which mutually have a phase difference, based on an external clock signal, a first phase interpolator configured to interpolate the first internal signal with the second internal signal in response to a first control signal and generate a first interpolation signal, a second phase interpolator configured to interpolate the first internal signal with the second internal signal in response to a second control signal and generate a second interpolation signal, and a selector configured to select any one of the first interpolation signal and the second interpolation signal in response to a selection signal and output the selected interpolation signal as an internal clock signal.
