ABSTRACT:
The semiconductor memory according to the present invention employs a plurality of sense amplifier drivers which individually control the sense amplifiers, or control groups of sense amplifiers, in the semiconductor memory. More specifically, the sense amplifier drivers control whether associated sense amplifiers are connected to sense amplifier array input/output lines. In this manner fewer sense amplifiers are connected to the sense amplifier array input/output lines, reducing overall current consumption.
