Classification: CPC G  H | IPC G  H

Claim 8:
9. An operation method of an input/output circuit, comprising the steps of:
precharging a first setup node and a second setup node to different voltage levels from each other based on differential input data during a precharging operation;
loading the differential input data to the first and second setup nodes precharged to the different voltage levels, during a loading operation; and
comparing and amplifying the data of the first and second setup nodes and outputting the amplified data during an output operation,
wherein the step of precharging the first and second setup nodes comprises:
precharging the first setup node based on a data strobe clock and a primary input data that is included in the differential input data; and
precharging the second setup node based on the data strobe clock and a secondary input data that is included in the differential input data.
