ABSTRACT:
Semiconductor memory device with duty correction circuit includes a clock edge detector configured to generate first and second detection pulses in response to a transition timing of a common clock signal in an initial measurement operation; a duty detector configured to compare the first and second detection pulses to output comparison result signals; and a code counter configured to control the duty detector based on the comparison signals outputted from the duty detector in the initial measurement operation.
