ABSTRACT:
A method for calibrating a timing clock is provided. The method includes the steps of calibrating a shift amount of an edge of a shift clock by using a period of the timing clock as a reference by detecting an edge of the timing clock more than once while changing the shift amount of the edge of the shift clock; shifting and generating the edge of the shift clock by a predetermined shift amount by the calibrated shift clock generating section; and calibrating a required delay amount for delaying the timing clock by time corresponding to the predetermined shift amount by detecting the edge of the shift clock shifted by the predetermined amount while changing a delay amount of the timing clock.
