A static random-access memory layout is provided in complementary metal oxide semiconductor (CMOS) technology with minimized cell area by sharing a diffusion well and contacts. This cell layout is similar to, but denser than, the layout of the cell illustrated in the preceding article, the cells being layouts of a known CMOS static random-access memory cell having first and second cross-coupled N channel transistors, third and fourth N channel input/output transistors, first and second P channel load transistors, a pair of bit/sense lines connectable to the cross-coupled transistors through the input/output transistors and a word line connected to the gate electrodes of the input/output transistors.
