Abstract
A high-speed, ultra-dense, via contact programmable ROM based on multiplexor cells is presented. High density is achieved by fully encoding n-bits of address space and programming the core with 2.sup.n bits of information per contact through the use of higher order logic techniques. Subfunction encoding is used to make substantial improvement to the area required for ROM structures. The programming is accomplished using via contacts between the top two metal layers. No transistors are used in the programmed core for the ROM, reducing the bit line load and helping to maintain a high level of performance.
