Abstract
A layout pattern of static random access memory at least includes a substrate, a plurality of fin structures on the substrate, a plurality of gate structures on the substrate and spanning the fin structures to form a plurality of transistors distributed on the substrate, the plurality of transistors include, a first pull-up transistor PU, a first pull-down transistor PD, a second pull-up transistor PU, a second pull-down transistor PD, a first pass gate transistor PG, a second pass gate transistor PG, a first read transistor RPD and a second read transistor RPG, and an additional fin structure, the additional fin structure is located between the fin structure of the first pass gate transistor PGand the fin structure of the second read transistor RPG.
