ABSTRACT:
A register controlled delay locked loop (DLL) usable in a semiconductor device is provided. The register controlled delay locked loop includes an internal clock generating unit generating a delayed clock signal and a reference clock signal, a first delay unit compensating for an amount of delay caused by a signal transmission path of the delayed clock signal, a phase comparator detecting a difference between the reference clock signal and the delayed clock signal and thereby generating a detection signal, a controller having a plurality of second delay units for controlling an amount of delay of the delayed clock signal in response to the detection signal, a driver driving a DLL clock signal, and an enable signal generator enabling the driver in response to an activation or non-activation signal of the semiconductor device.
