A clock signal duty correction circuit includes: a first transition timing control unit configured to generate a first control signal for controlling a rising timing of a duty correction clock signal by using a clock signal; a second transition timing control unit configured to generate a second control signal for varying a falling timing of the duty correction clock signal by using the clock signal according to a code signal; and a differential buffer unit configured to generate the duty correction clock signal, whose rising time or falling time is adjusted, in response to the first control signal and the second control signal.
