A semiconductor device increases the data transfer rate in transferring {HEAD ~ data output} from an input/output sense amplifier via {TAIL ~ a global data bus line} by reducing the swing width of the data placed on the global data bus line, thereby achieving an enhancement in high frequency operation characteristics while suppressing generation of data errors
