Abstract
A semiconductor device including an edge synchronizer which outputs a synchronized strobe signal generated by synchronizing a transition time point of a strobe signal with clock edges of a main clock or a sub clock, a detector which outputs a phase determination signal indicating a phase difference between the main clock and the sub clock in response to the synchronized strobe signal, and a duty ratio corrector which adjusts a duty ratio of the main clock and the sub clock in response to the phase determination signal.
