Abstract
A memory circuit including a memory cell array. The memory cell array has a first word line group connected to a pair of memory cells associated with a first bit line pair including first and third bit lines, and a second word line group, connected to a pair of memory cells associated with a second bit line pair including second and fourth bit lines. First and second sense amplifier groups are positioned one on each side of the memory array, and are connected to the first and second bit line pair, respectively. When any word line of the first word line group is driven, the first sense amplifier group is activated to drive the first word line group in reverse phase, and the second sense amplifier group is kept in the inactive state to keep the second word line group at the precharge level.
