Abstract
A semiconductor apparatus receives a first clock signal and a second clock signal. The semiconductor apparatus configured to perform a training operation internally, the training operation being an operation of internally correcting a phase difference between the first clock signal and the second clock signal by dividing the first clock signal to generate multi-phase signals, detecting phase difference between the second clock signal and the multi-phase signals, and adjusting phases of the multi-phase signals according to a result of the detecting of the phase difference.
