ABSTRACT:
A semiconductor device is disclosed which 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. The semiconductor device may include a data transfer unit which receives first data, and outputs second data obtained by driving the first data to a predetermined level to a data transfer line; a data receiver which receives the second data transferred via the data transfer line; a delay which outputs a plurality of delay signals respectively obtained by delaying the second data outputted from the data transfer unit by different delay periods; a delay controller which selects one of the delay signals in accordance with an operation mode of the semiconductor device, and outputs at least one adjustment signal for adjusting a driving period of the data transfer unit for the first data based on the delay period of the selected delay signal; and a transfer controller which receives the first data and the at least one adjustment signal, and outputs at least one transfer control signal for controlling the operation of the data transfer unit, based on the received first data and adjustment signal.
