1. A memory system comprising:
a first group of memory cells;
a second group of memory cells abutted to the first group of memory cells;
a first sub-word line driver disposed opposite the first group of memory cells from the second group of memory cells, wherein the first sub-word line driver is configured to apply a first control signal to the first group of memory cells; and
a second sub-word line driver disposed opposite the second group of memory cells from the first group of memory cells, wherein the second sub-word line driver is configured to apply a second control signal to the second group of memory cells;
wherein the first sub-word line driver, the first group of memory cells, the second group of memory cells, and the second sub-word line driver are disposed next to one another in such a sequence along a lateral direction.
