Abstract

Some embodiments relate to an SRAM cell layout including upper and lower cell edges and left and right cell edges. A first power rail extends generally in parallel with and lies along the left cell edge or the right cell edge. The first power rail is coupled to a first power supply. A second power rail extends generally in parallel with the first power rail and is arranged equidistantly between the left and right cell edges. A first bitline extends in parallel with the first power rail and the second power rail and is arranged to a first side of the second power rail. A second bitline, which is complementary to the first bitline, extends in parallel with the first power rail and the second power rail and is arranged to a second side of the second power rail.
