Abstract
A memory cell array includes a first bank of memory cells, a second bank of memory cells adjacent to the first bank of memory cells, a first set of bit lines and a second set of bit lines. The first set of bit lines extend in a first direction, is coupled to the first bank of memory cells, and is on at least a first metal layer above a front-side of a substrate. The second set of bit lines extend in the first direction, is coupled to the second bank of memory cells, and is on at least a second metal layer below a back-side of the substrate opposite from the front-side of the substrate.
