Classification: CPC G  H | IPC G  H

Claim 11:
12. A data processing system comprising:
a host device configured to provide differential input data and data frequency information; and
a data processing device configured to input and output the differential input data based on a data strobe clock with a duty rate that corresponds to the data frequency information,
wherein the data processing device comprises:
a clock generation circuit configured to adjust the duty rate of the data strobe clock and generate a final data strobe clock based on the data frequency information; and
an input/output circuit comprising an input circuit configured to load the differential input data to setup nodes based on the final data strobe clock, an amplifier circuit configured to amplify the data that is loaded to the setup nodes and configured to output the amplified data, and a precharging circuit configured to precharge the setup nodes based on the final data strobe clock and the differential input data.
