Abstract: An apparatus includes a memory circuit and a word-line driver circuit. The memory circuit includes a plurality of rows of memory cells, each memory cell in a corresponding row having pass transistors connected to a shared word-line. The word-line driver circuit is configured and arranged to enable pass transistors of a first set of memory cells of the memory circuit by applying a first voltage to word-lines of the first set of memory cells, disable pass transistors of a second set of memory cells of the memory circuit by applying a second voltage to word-lines of the second set of memory cells, and mitigate leakage of pass transistors of a third set of memory cells of the memory circuit by applying a third voltage to word-lines of the third set of memory cells, wherein the third voltage is between the first and second voltages.

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.
