  • Delay circuit with reset-based forward path static delay
    Patent number: 7276947
    Abstract: A delay locked loop circuit and method of operating the same. The delay locked loop circuit comprises a forward delay path having a variable delay portion and a static delay portion, wherein the static delay portion includes a static delay element, a feedback path for generating a feedback signal responsive to an output signal, and a phase detector for comparing the phase of an input signal and the phase of the feedback signal and for generating a variable control signal for controlling the amount of delay provided by the variable delay portion, wherein the static delay element is activated in response to a static control signal indicative of the variable delay portion being unable to lock the output signal to the input signal. Because of the rules governing Abstracts, this Abstract should not be used to construe the claims.

  • Circuit and method for controlling a clock synchronizing circuit for low power refresh operation
    Publication number: 20060274592
    Abstract: A method and apparatus is provided for idling a clock synchronizing circuit during at least a portion of time during execution of a refresh operation in a memory device. In a memory device receiving an external clock signal, a method and apparatus for executing a refresh operation is provided that includes initiating at least one refresh operation in the memory device, and ceasing generation of an internal clock signal timed with respect to the external clock signal for at least a portion of the time in which at least one refresh operation takes to complete.
