Abstract
Provided is a semiconductor device for compensating for an internal skew without training with an external device. The semiconductor device includes a signal generating unit configured to generate and output a reference signal, a first receiving unit configured to receive the reference signal and output a first output signal, a second receiving unit configured to receive the reference signal and output a second output signal, a delay unit configured to delay the first output signal by a certain time and output a delayed signal, a sampling unit configured to sample the second output signal based on the delayed signal and output sampling data, and a skew controlling unit configured to control the delaying unit based on the sampling data.
