REGISTER CONTROL DELAY LOCKED LOOP AND SEMICONDUCTOR DEVICE PROVIDED WITH THE SAME

摘要

PURPOSE: A register control delay locked loop and a semiconductor device provided with the same are provided to minimize an unnecessary power consumption and contribute to developing a low power device. CONSTITUTION: A semiconductor device provided with a register control delay locked loop and an inner circuit for utilizing a DLL clock includes a DLL clock enable signal generator(53) for generating a DLL clock enable signal(dll_en) to enable/disenable the DLL clock applied to the inner circuit in response to an activation information and a non-activation information for the semiconductor device.
