Abstract
A local sense amplifier circuit in a semiconductor memory device, the local sense amplifier circuit including a local data sensing unit configured to amplify a voltage difference between a local input/output (I/O) line pair based on a local sensing enable signal to provide the amplified voltage difference to a global I/O line pair, the local I/O line pair including a first local I/O line and a second local I/O line, and a local I/O line control unit including a first capacitor and a second capacitor, the first capacitor increasing a voltage level of the first local I/O line based on the local sensing enable signal, the second capacitor increasing a voltage level of the second local I/O line based on the local sensing enable signal.
