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