    摘要: The present invention comprises a memory device for compensating for a clock skew that generates a centering error, and a method of compensating for the clock skew. To compensate for a clock skew that causes a centering error between an external clock signal and an output data signal, the memory device includes a phase detector (PD) and an up-down counter. The PD detects a phase difference between the output data signal and the external clock signal and generates an up signal or a down signal depending on the detected phase difference. The up-down counter is enabled by a calibration signal that directs a compensation of the skew and generates an offset code in response to the up signal or the down signal. The offset code is fed back to a delay locked loop (DLL) circuit and aligns the middle points of the output data signal with the edges of the external clock signal.

    摘要: In an output driver circuit and method, a control circuit generates a control signal in response to a current internal data signal. An output driver generates an output data signal in response to the control signal. A pre-emphasis circuit adjusts a current flowing through a node having the control signal generated thereon in response to a previous internal data signal. The pre-emphasis circuit may also adjust the output signal in response to the previous internal data signal.

    摘要: The output signal from an output driver is compared with first and second reference voltages. A first comparison output signal is generated which exhibits a voltage transition when the output signal reaches the first reference voltage, and a second comparison output signal is generated which exhibits a voltage transition when the output signal reaches the second reference voltage. First and second pulse widths values are then compared. The first pulse width value corresponds to a time delay difference between the voltage transition of the first comparison output signal and the voltage transition of the second comparison output signal, and the second pulse width value corresponds to a target slew rate of the output signal from the output driver. The slew rate of the output signal is decrease when the first pulse width value is smaller than the second pulse width value, and the slew rate of the output signal is increased when the first pulse width value is larger than the second pulse width value.

    摘要: A duty cycle correction circuit and a delay locked loop (DLL) including the duty cycle correction circuit, are capable of controlling their operation in order to correctly analyze the cause of generation of a duty cycle error when the duty cycle error is generated in the DLL. The duty cycle correction circuit selectively outputs to a DLL core duty cycle offset information for controlling a duty cycle of an internal clock signal synchronized to an external clock signal under the control of a switching control signal. The DLL corrects the duty cycle of a reference clock signal according to the duty cycle offset information, thereby outputting a reference clock signal having a 50% duty cycle.
