Abstract
A semiconductor apparatus includes an odd data clock buffer group configured to maintain or shift a phase of a multi-phase source clock signal, and output a first multi-phase clock signal, an even data clock buffer group configured to maintain or shift a phase of the multi-phase source clock signal, and output a second multi-phase clock signal, an odd data output buffer group configured to drive odd data in response to the first multi-phase clock signal and output the driven data to an odd data pad group, and an even data output buffer group configured to drive even data in response to the second multi-phase clock signal and output the driven data to an even data pad group, wherein the phases of clock signals of the first and second multi-phase clock signal are different from each other.
