Abstract
A semiconductor device includes a division period signal generation circuit and a clock sampling circuit. The division period signal generation circuit generates a division period signal which is enabled in synchronization with a write period that is set according to a write command and latency information. The clock sampling circuit samples an internal strobe signal to output a sampling clock signal in response to the division period signal and the internal strobe signal during a sampling period. The sampling period is set to be longer than the write period.
