  • Delay circuit and semiconductor apparatus including the same
    Patent number: 8823431
    Abstract: A delay circuit includes a clock delay line, a command delay line, a delay line control block, and a shared shift register block. The clock delay line delays an input clock and generates a delayed clock. The command delay line delays a command signal and generates a delayed command signal. The delay line control block generates a control signal according to a result of comparing phases of a feedback clock which is generated as the delayed clock is delayed by a modeled delay value and the input clock. The shared shift register block sets delay amounts of the clock delay line and the command delay line to be substantially the same with each other, in response to the control signal.
