摘要:
An embodiment is a method for forming a static random access memory (SRAM) cell. The method comprises forming transistors on a semiconductor substrate and forming a first linear intra-cell connection and a second linear intra-cell connection. Longitudinal axes of the active areas of the transistors are parallel. A first pull-down transistor and a first pull-up transistor share a first common gate structure, and a second pull-down transistor and a second pull-up transistor share a second common gate structure. The first linear intra-cell connection electrically couples active areas of the first pull-down transistor and the first pull-up transistor to the second common gate structure. The second linear intra-cell connection electrically couples active areas of the second pull-down transistor and the second pull-up transistor to the first common gate structure.
