Abstract
A resister controlled delay locked loop (DLL) is provided which is capable of reducing current consumption by operating the DLL loop when the semiconductor device is only at an operation mode. A semiconductor device having the register controlled DLL and an internal circuit synchronized with a DLL clock signal output from the register controlled DLL, includes an enable signal generator generating an enable signal for the register controlled DLL to control a generation of the DLL clock signal in response to an activation or non-activation signal of the semiconductor device.
