Abstract
The present invention provides a layout pattern of a static random access memory (SRAM), comprising at least two inverters coupled to each other for storing data, each inverter comprising an L-shaped gate structure on a substrate, the L-shaped gate structure includes a first portion arranged along a first direction and a second portion aligned along a second direction, wherein the first portion crosses a first diffusion region to form a pull-up device, and the first portion crosses a second diffusion region and a third diffusion region to form a pull-down device, and each of the inverters includes a local interconnection layer, crossing the second diffusion region and the third diffusion region.
