ABSTRACT:
There is provided a semiconductor memory device, including: a plurality of bank groups each comprising a plurality of banks; a plurality of data pads grouped by a predetermined number for receiving data for the bank groups, wherein the data pads are divided into a plurality of first pad groups receiving data and a plurality of second pad groups selectively receiving data according to a data input/output option value; a first driving unit configured to drive data input via the first pad group to transfer the data input via the first pad group to the bank group corresponding to the first pad group; a second driving unit configured to drive data input via the second pad group to transfer the data input via the second pad group to the bank group corresponding to the second pad group; and a third driving unit configured to drive data input via the first pad group to transfer the data input via the first pad group to the bank group corresponding to the second pad group in response to the data input/output option value.
