The principles of a computer-assisted design program are disclosed for a random-access memory (RAM). The program aids in the design of a RAM which has optimized X and Y dimensions for improved performance and chip area utilization. The X dimension in mils is given by the relation X equals N word length, where N is an integer. Word length is the number of bits in the word size selected for storage in the memory. The Y dimension is given by the relation Y equals the number of words stored in the memory N. The X and Y dimensions are in orthogonal relation. The X dimension is divided into a plurality of diffusion lines in the Y direction, one for each bit in the word length, disposed on the surface of the semiconductor chip.
