Abstract
A semiconductor device includes a detection signal generation circuit generating a detection signal by detecting a phase difference of an input signal and an internal clock, and generating delayed input signals by delaying the input signal. The semiconductor device further includes an output enable signal generation circuit outputting an output enable signal by selecting one of the delayed input signals in response to the detection signal and latching the selected one of the delayed input signals in synchronization with the internal clock. The output enable signal may initiate a data transfer operation.
