摘要:
Various embodiments are directed to different methods and systems relating to design and implementation of memory cells such as, for example, static random access memory (SRAM) cells. In one embodiment, a memory cell may include a first layer of conductive material and a second layer of conductive material. The first layer may include a first gate region and a first interconnect region, and the second layer of conductive material may include a second gate region and a second interconnect region. It will be appreciated that the various techniques described herein for using multiple layers of conductive material to form interconnect regions and/or gate regions of memory cells provides extra degrees of freedom in fine tuning memory cell parameters such as, for example, oxide thickness, threshold voltage, maximum allowed gate voltage, etc.
