Abstract
A semiconductor device includes a phase difference detection circuit configured to generate a detection signal by detecting a phase difference of a clock and a strobe signal, the detection signal being generated at a logic level of the strobe signal in synchronization with the clock, and configured to generate a write clock by delaying the strobe signal. The semiconductor device also includes a control signal generation circuit configured to store the detection signal, in synchronization with the write clock, and configured to output the stored detection signal as a control signal.
