Abstract
An internal clock generation circuit includes an interpolation clock generation circuit and a locked clock generation circuit. The interpolation clock generation circuit generates an interpolation clock signal from a division clock signal in response to a switching control signal and a current control signal. The locked clock generation circuit includes an oscillator and generates a locked clock signal for generating an internal clock signal from the interpolation clock signal.
