The first and second high aspect ratio voltage rails each have a height-to-width ratio greater than 1.0.The height of each respective first and second high aspect ratio voltage rail is greater than each respective width. Employing the first and second high aspect ratio voltage rails allows each to have a cross-sectional area that limits the resistance and corresponding IR drop.
