Abstract
The invention provides a layout pattern cell of a static random access memory (SRAM), which at least comprises a first SRAM cell, a plurality of gate structures spanning a plurality of fin structures, so as to form a first pull-up transistor, a second pull-up transistor, a first pull-down transistor, a second pull-down transistor, a first access transistor, a second access transistor, a third access transistor, a fourth access transistor, a first parasitic transistor and a second parasitic transistor located on a substrate, the first parasitic transistor and the first pull-down transistor span the same fin structure, and the fin structure spanned by the first parasitic transistor and the first pull-down transistor is a continuous structure.
