ABSTRACT:
A semiconductor memory device includes a repeater located at a global input/output (GIO) line. The repeater buffers and transmits data between a data pad and a plurality of banks. The semiconductor memory device also includes a repeater control unit adapted to control the operation of the repeater in response to a read/write command associated with one of the plurality of banks. When a read or write operation is performed for the banks located farthest from the data pads, the repeater on the GIO line buffers the GIO signal, and thereby reduces the load of the GIO line, decreases the delay of the GIO signal, and improves the slope of the GIO signal. As a result, the semiconductor memory device is useful during high speed operations.
