Claim 0:
1. A semiconductor memory device comprising:
a plurality of data pads connected to a memory controller;
a plurality of wordlines extending in a row direction and arranged in a column direction, the plurality of wordlines being grouped into a plurality of wordline groups such that each wordline group includes wordlines adjacent in the column direction, a selection wordline being selected based on a row address;
a plurality of memory cells connected to the plurality of wordlines;
a plurality of global input-output lines extending in the column direction and arranged in the row direction to transfer data between the plurality of data pads and the plurality of memory cells, the plurality of global input-output lines being cut into a plurality of line segment groups respectively corresponding to the plurality of wordline groups; and
a plurality of intra-bank switches configured to control, based on the row address, electrical connections between two line segment groups among the plurality of line segment groups, the two line segment groups being adjacent in the column direction and included in one memory bank,
wherein the plurality of wordline groups include a first wordline group and a second wordline group,
wherein the two line segment groups include a first line segment group and a second line segment group such that the first line segment group is nearer to the plurality of data pads than the second line segment group,
wherein the plurality of intra-bank switches are turned off to electrically separate the first line segment group and the second line segment group when the selection wordline is included in the first wordline group corresponding to the first line segment group, and
wherein the plurality of intra-bank switches are turned on to electrically connect the first line segment group and the second line segment group when the selection wordline is included in the second wordline group corresponding to the second line segment group.
