ABSTRACT:
A method of operating a delay locked loop is comprised of producing a first output signal in response to a first lock point. A new lock point is measured, or otherwise determined, while continuing to produce the first output signal. Thereafter, a second output signal is produced in response to the new lock point. The new lock point data may be loaded into the delay locked loop while the delay locked loop continues to produce the first output signal. The delay locked loop switches from producing the first output signal, responsive to a first lock point, to producing the second output signal, responsive to the new lock point, in response to various conditions such as control signals, e.g. an auto refresh command, a precharge all command, a mode register load command, a power down entry, a power down exit (among others), in response to a timer, e.g., an internal timer (among others), or in response to environmental condition signals, e.g., a temperature sensor output signal (among others). Circuits and systems using the disclosed method are also disclosed. Because of the rules governing abstracts, this abstract should not be used to construe the claims.
