<p>A semiconductor device includes a delay part configured to assign a delay to an input signal, a phase detector configured to detect a phase of an output signal output from the delay part, a setting part configured to set a stable operations range of the phase of the output signal based on phase information output from the phase detector, and an error detector configured to set an acceptable range corresponding to the stable operations range, determine whether a phase of the output signal falls within the acceptable range, and change the acceptable range based on an extraneous factor of an input signal of the delay part.</p> |
