ABSTRACT:
A sense amplifier driver activates a plurality of sense amplifiers coupled to respective digit lines in each of a plurality of memory-cell arrays. The sense amplifiers each have first and second activation nodes. The sense amplifier driver includes a plurality of drive circuits each coupled to the first and second activation nodes of the sense amplifiers in at least one of the memory-cell arrays. The first activation nodes of the sense amplifiers in at least one of the memory-cell arrays are coupled to a plurality of drive circuits so that the plurality of drive circuits drive the first activation nodes of the sense amplifiers in at least one of the memory-cell arrays in parallel.
