  • Patent number: 5761142
    Abstract: A semiconductor memory device includes a plurality of sense amplifiers which are divided into two groups. There are provided drive wires each extending to an associated one of the sense amplifier groups and being used to independently drive the associated group. The length of each drive wire being thereby reduced up to a half, to operated at a high speed.
