Abstract
A duty cycle correction circuit includes a duty correction circuit, an information generation circuit and a duty control circuit. The duty correction circuit corrects a duty rate of an input clock signal based on a duty control code to generate an output clock signal. The information generation circuit compares a difference between operation power voltages based on an operation mode to generate voltage information. The duty control circuit receives the voltage information from the information generation circuit and generates the duty control code that includes the voltage information based on a duty rate of the output clock signal.
