An integrated circuit includes a delay lock circuit to synchronize an internal clock signal with an external clock. The integrated circuit, in one embodiment, is a memory device. The delay lock circuit includes a delay line, a delay register to control a delay time of the delay line, and a non-volatile register. The non-volatile register stores an initial value for the delay register. The delay register is pre-loaded with the contents of the non-volatile register to decrease the time need to synchronize the clock signals.
