摘要：A system on chip (SOC) characterized by nitride read only memory (NROM) and
read only memory (ROM) has a P-type substrate, and at least an NROM area and a read
only memory area defined on the surface of the substrate. ONO layers are disposed
along a first direction and positioned in the NROM area and the read only memory area.
A bit line is positioned in the substrate between each ONO layer. Oxide layers are
positioned atop each bit line. A plurality of word lines disposed along a second direction
covers each ONO layer in the NROM area and the read only memory area, so as to form a
plurality of NROM cells at the intersection of the NROM area and each ONO layer, and to
form a plurality of read only memory cells at the intersection of the read only memory
area and each ONO layer. A doping area is optionally positioned at a bottom side of a
read only memory cell, so as to cause the read only memory cell to have at least two
different threshold voltages and to form ROM code.
