A semiconductor device includes a receiving circuit, an oscillator code generation circuit, and a control circuit. The receiving circuit receives a clock signal and data, delays the clock signal by a clock delay time to generate an internal clock signal, and captures the data with the internal clock signal. The oscillator code generation circuit generates an oscillation signal having a period of N times the clock delay time, wherein N is a positive integer, and generates an oscillator code based on the oscillation signal. The control circuit controls the oscillator code generation circuit in response to at least one external signal. The at least one external signal including a chip enable signal.
