Abstract: An operating method of a delay locked loop (DLL) circuit for a semiconductor memory device is disclosed. The DLL circuit may include a plurality of sub-circuits. The method may include calculating an additive latency value based on predetermined parameters, and controlling a set of the plurality of sub-circuits of the DLL circuit to be maintained in a turn-off state based on the calculated additive latency value, during a period of time after the semiconductor device receives an operation command in a power saving mode.

Abstract: A delay-locked loop circuit includes a phase detector and a coarse-lock detector. The phase detector receives a feedback clock and a first clock to generate first and second phase detecting signals, respectively. The coarse-lock detector generates a coarse-lock signal based on changes of phase of the first and second phase detecting signals.
