    摘要: A clock data recovery apparatus includes a phase looked loop unit, a voltage control delay line, a phase detection unit, a charge pump unit, and a loop filter unit. The phase looked loop unit outputs a plurality of clock signals which are different from each other in phase and of which frequency is lower than that of data. The voltage control delay line outputs recovered clock signals by delaying the clock signals according to input voltage levels. The phase detection unit outputs recovered data in synchronization with the clock signals, respectively and outputs increment and decrement signals which have wider pulse width than the data by comparing the recovered clock signals with the data. The charge pump unit outputs a corresponding current in response to the increment and decrement signals. The loop filter unit determines an amount of delay in the voltage control delay line by outputting the voltage.

    摘要: An impedance matching circuit of a semiconductor memory device performs a ZQ calibration with initial values that reflect an offset error according to variations in a manufacturing process. The impedance matching circuit includes a first pull-down resistance unit, a first pull-up resistance unit, and a code generation unit. The first pull-down resistance unit supplies a ground voltage to a first node, thereby determining an initial pull-down code. The first pull-up resistance unit supplies a supply voltage to the first node, thereby determining an initial pull-up code or a voltage level on the first node. The code generation unit generates pull-down and pull-up calibration codes using the initial pull-down and pull-up codes as respective initial values.
