Abstract:
A static random access memory (SRAM) device is provided in accordance with some embodiments. The SRAM device comprises a plurality of two-port SRAM arrays, which comprise a plurality of two-port SRAM cells. Each two-port SRAM cell comprises a write port portion, a read port portion, a first plurality of metal lines located in a first metal layer, a second plurality of metal lines located in a second metal layer, a third plurality of metal lines located in a third metal layer a plurality of edge cells, a plurality of well strap cells, and a plurality of jumper structures. Each jumper structure comprises first, second, and third metal landing pads located in the second metal layer and electrically connecting metal lines of the first and third metal layers.
