    Abstract: A semiconductor device includes: a memory circuit having a plurality of quadrants arranged at corners of the memory circuit and surrounding a bank control component; wherein a first quadrant of the plurality of quadrants includes a first bit cell core and a first set of input output circuits configured to access the first bit cell core, the first quadrant defined by a rectangular boundary that encloses portions of two perpendicular edges of the memory circuit; wherein a second quadrant of the plurality of quadrants includes a second bit cell core and a second set of input output circuits configured to access the second bit cell core, the second quadrant being adjacent the first quadrant, wherein a border between the first quadrant and the second quadrant defines a first axis about which the first quadrant and the second quadrant are symmetrical.

    Abstract: Static random access memory (SRAM) bit cells employing asymmetric width read and write word lines (WWL) for reduced memory write latency and improved memory write access performance, and related fabrication methods are disclosed. In exemplary aspects, the SRAM bit cell employs an increased width write word line based on a circuit cell layout area savings achieved by employing a reduced width read word line. Increasing the width of the write word line can reduce the resistance of the write word line and decrease memory write latency to the SRAM bit cell as a result. In certain exemplary aspects, the metal line pitch and minimum distance between metal lines of the SRAM bit cell can be maintained for maintaining fabrication compatibility with existing fabrication processes with decreasing the resistance of the write word line of the SRAM bit cell.
