摘要： A delay locked loop (DLL) circuit has a first delay line that delays a received external clock signal for a fine delay time and then outputs a first internal clock signal; a duty cycle correction unit that corrects a duty cycle of the first internal clock signal and then outputs a second clock signal; a second delay line that delays the second clock signal for a coarse delay time and then outputs a second internal clock signal; and a phase detection and control unit that detects the difference between the phases of the external clock signal and the fed back second internal clock signal, and controls the fine delay time and the coarse delay time. The DLL circuit performs coarse locking and fine locking by using different type delay cells, and thus consumes a small amount of power and robustly withstands jitter and variation in PVT variables.

摘要： A data output buffer includes an output terminal, a buffer and a pull-down driver. The output terminal is coupled to a first end of a transmission line, the transmission line being coupled to a pull-up termination resistor at a second end. The buffer pulls up the output terminal to a first power supply voltage and pulls down the output terminal to a second power supply voltage based on an output data signal. The pull-down driver pre-emphasizes an initial stage of a pull-down driving operation of the output terminal based on the output data.
