  • NAND stack ROM
    Patent number: 4980861
    Abstract: Faster access time is achieved in a NAND stack ROM by eliminating depletion mode decode transistors, thus reducing column capacitance. Horizontal ground straps of diffusion are eliminated to reduce chip area by running virtual ground lines vertically through the array. Adjacent columns are tied to alternating sense amplifiers utilizing a simple multiplexer connected to the virtual ground lines.
