Circuit and method of fabricating a memory cell for a static random access memory

摘要

A circuit and method is disclosed for a memory cell for a static random access memory. The memory cell includes a pair of cross-coupled CMOS logic inverters that are connected together to form a latch, and a pair of p-channel transmission gate transistors that are connected to the logic inverters for selectively providing access to the latch. The layout of the memory cell includes a rectangular active area in which the p-channel transistors of the memory cell are located. The rectangular active area abuts a similar active area of an adjacent memory cell along a row of memory cells so as to form a single rectangular active area for the p-channel memory cell transistors. The rectangular active area reduces the occurrence of fabrication-related phenomena that adversely effect the performance of the memory cell.
