Abstract
A semiconductor device includes a pre-pulse generation circuit configured to generate a pre-pulse, based on a write shifting pulse and a write leveling activation signal; a write control signal generation circuit configured to generate a write control signal, based on the pre-pulse and a division clock; and a write leveling control circuit configured to generate detection data including information on a phase difference between a data clock and a system clock, based on the pre-pulse and the division clock.
