Abstract
A method of controlling a power control circuit includes enabling a power cutoff signal when a delay locking operation of a Delay Locked Loop (DLL) circuit is completed, disabling the power cutoff signal for a predetermined time, and detecting a phase difference between a reference clock and a feedback clock to re-determine, on the basis of the detection result, whether or not to enable the power cutoff signal.
