ABSTRACT:
A semiconductor memory device of the claimed invention, having an active state for performing a read or write operation and an inactive state except for the active state includes a data input/output (I/O) line; a pull-up latch unit for pulling-up the data I/O line when the semiconductor memory device is in the inactive state; a pull-down latch unit for pulling-down the data I/O line when the semiconductor memory device is in the inactive state; and a selection unit for selectively driving one of the pull-up latch unit and the pull-down latch unit.
