Dual port memory cell with improved access resistance
Abstract:
The present disclosure is directed to a circuit layout of a dual port static random-access-memory (SRAM) cell. The memory cell includes active regions in a substrate, with polysilicon gate electrodes on the active regions to define transistors of the memory cell. The eight transistor (8T) memory cell layout includes a reduced aspect ratio and non-polysilicon bit line discharge path routing by positioning an active region for the first port opposite an active region for the second port and consolidating power line nodes at a central portion of the memory cell.
