Abstract
A semiconductor device includes a sampling unit suitable for sampling a logic value of an input signal based on an edge of an operation clock to output a sampling signal, an edge detection unit suitable for detecting an edge of the input signal based on the sampling signal, and a phase control unit suitable for controlling a phase of the operation clock while periodically changing a value of a clock delay code at each predetermined period and substituting a code value, which is obtained by calculating a value of the clock delay code corresponding to a time point at which an operation of the edge detection unit is completed and a value of a pre-phase code determined based on the sampling signal, for the clock delay code.
