Abstract
A read-only memory (ROM) device includes memory cells, bit-line pairs, a virtual ground line, and a programmable metal track. The memory cells are arranged in an array of rows and columns. Each memory cell stores two bits of data. The virtual ground line is disposed vertically and shared by two adjacent columns. The programmable metal track connects a memory cell to the virtual ground line based on a value of the two bits of data stored in the memory cell.
