    摘要: A delay locked loop includes a closed loop circuit configured to generate preliminary delay information, a control unit configured to update the preliminary delay information into delay information in response to a control signal, and a first delay unit configured to delay an input clock signal by a first delay value determined by the delay information and generate an output clock signal.

    摘要: An internal clock signal generation circuit is capable of controlling a unit delay time depending on a frequency of an external clock signal. The internal clock signal generation circuit includes an internal clock signal generation unit configured to generate an internal clock signal corresponding to a plurality of unit delay cells enabled in response to a control signal, and a unit delay time control unit configured to detect a frequency of an external clock signal and control a unit delay time of each of the plurality of unit delay cells.
