Abstract
A DLL circuit including a first clock signal dividing block configured to selectively divide a frequency of a reference clock signal according to whether a lock completion signal is enabled, a phase comparing block configured to generate a phase comparison signal by comparing phases of a clock signal transmitted from the first clock signal dividing block with a feedback clock signal, and an operation mode setting block configured to generate the lock completion signal in response to the phase comparison signal is described herein.
