Abstract
Systems and methods are provided for operating a delay locked loop during a reset. The systems and methods provide for activating a reset mode signal to prevent a phase lock signal from forcing the DLL out of a reset, and deactivating the reset mode signal only after at least one shifting operation is performed to allow the phase lock signal to correctly allow the DLL to be out of the reset.
