On a layout, pass gates connecting to the two ports are disposed near pull down transistors of corresponding memory nodes. A cell layout structure of the SRAM cell structure is centrosymmetric. In a first subunit layout structure, a pass gate and a first pull down transistor share the same active region, and an active region of the other pull down transistor is disposed between active regions of the first pull down transistor and a first pull up transistor. The present application improves the symmetry of read paths of the two memory nodes from two ports thus the symmetry of read currents, therefore the variation of the electrical performance of PMOS transistors is reduced and the stability of the electrical performance of the PMOS transistors is improved."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dual-port SRAM","description":"The present application discloses a dual-port SRAM having two ports.
