Latest Patents

Chenglei Guo holds a patent for a dual-port SRAM. The patent discloses a dual-port SRAM that features two ports. In the layout, pass gates connecting to the two ports are strategically placed near pull-down transistors of the corresponding memory nodes. The cell layout structure of the SRAM is designed to be centrosymmetric. In the first subunit layout structure, a pass gate and a first pull-down transistor share the same active region, while the active region of the other pull-down transistor is positioned between the active regions of the first pull-down transistor and a first pull-up transistor. This design improves the symmetry of read paths from the two ports, thereby enhancing the symmetry of read currents. As a result, the variation in the electrical performance of PMOS transistors is reduced, leading to improved stability in their electrical performance.
