    摘要: A data transmission/reception system can lessen a skew between data and clock signal by substantially reducing a data reception error. The data transmission/reception system using a first clock signal and a second clock signal having a phase difference corresponding to a half of data bit period as compared with the first clock signal includes a skew information extracting unit and a timing control unit. The skew information extracting unit obtains and outputs skew edge information data necessary for a skew removal by sampling data transmitted in a training operating mode as one of the first and second clock signals in a receiving side. The timing control unit receives the skew edge information data through a transmitting side, and compares its phase with a phase of the transmitted data and controls a timing between transmission data and a transmission sampling clock signal applied to a transmission output unit according to the phase comparison result. Time taken in a training operation can be relatively shortened, and circuits of the receiving side can be simplified and power consumption can be relatively reduced.

    摘要: A method of determining timing skew between data outputs of a memory device can include writing a predetermined data pattern to a memory device at a first operational frequency that is less than a normal operational frequency used to write non-predetermined data to the memory device. The memory device is read to output the predetermined data pattern therefrom at a second operational frequency that is greater than the first operational frequency and about equal to a normal operational frequency used to read non-predetermined data from the memory device. Timing skew is determined between outputs from the memory device based on the actual time when the predetermined data is provided from the memory device.

    摘要: Circuits, methods and systems are provided to reduce skew between a first digital signal that is transmitted by a first driver circuit over a first signal line, and a second digital signal that is transmitted by a second driver circuit over a second signal line. Skew may be reduced by sourcing or sinking additional current to or from the first signal line in response to the first digital signal and the second digital signal transitioning to opposite logical values, and otherwise refraining from sourcing or sinking the additional current to or from the first signal line. Skew may also be reduced between the first digital signal that is transmitted by the first driver circuit over the first signal line and a third digital signal that is transmitted by a third driver circuit over a third signal line by sourcing or sinking additional current to or from the first signal line in response to the first digital signal and the third digital signal transitioning to opposite logical values, and to otherwise refrain from sourcing or sinking the additional current to or from the first signal line.
