    摘要： A phase-locked loop (PLL) having a bias generator capable of reducing noise is provided. In the PLL, a voltage controlled oscillator is driven using a regulator. The bias generator, which applies a bias voltage to the regulator, is configured to have opposite power noise characteristics to the power noise characteristics of the regulator, such that the occurrence of jitter in the PLL is reduced.

    摘要： A semiconductor memory device comprises a variable delay unit and a data trainer. The variable delay unit is configured to generate a write data signal by delaying a write data driving signal by different amounts of time depending on whether the semiconductor memory device is in a data training mode or a normal operating mode, and further configured to generate a read data driving signal by delaying a read data signal by different amounts of time in the data training mode and the normal operating mode. The data trainer is configured to be activated in the data training mode, and while activated, receive the write data signal, compare the write data signal with a predetermined write pattern, perform a data training mode operation, and output the read data signal with a predetermined read pattern.

    摘要： A data receiver in a memory device includes an integration unit, a sense amplification unit and a latch unit. The integration unit integrates a data signal to generate a first equalization signal in response to a sampling feedback signal. The data signal includes a plurality of data that are sequentially received. The sense amplification unit senses the first equalization signal to generate a second equalization signal in response to a sensing feedback signal. The latch unit latches the second equalization signal to generate a sampling data signal
