ABSTRACT:
A sense amplifier control circuit supplies a first potential to the sense amplifiers of a semiconductor memory through a set of first control transistors, each coupled in parallel to at least two and at most four sense-amplifier nodes. The first transistors are switched by a first control signal line. A second potential may be supplied to the sense amplifiers through a similar set of second control transistors, which are switched by a second control signal line. The first and second control signal lines may be driven independently, or one or both control signal lines may be driven by a set of drivers coupled in parallel between the two control signal lines.
