  • Delay apparatus for delay locked loop
    Patent number: 7710178
    Abstract: A delay apparatus for a delay locked loop includes a plurality of delay devices that are formed by modeling a plurality of signal processing structures through which a delay locked loop clock output from a delay locked loop reaches an output circuit of a semiconductor memory apparatus from an output terminal of the delay locked loop. At least one of the plurality of delay devices is composed of a variable delay device in which a delay time varies according to a change in operation voltage.
