  • Patent number: 9960045
    Abstract: In a 3D NAND device, the charge trap region of a memory cell is formed as a separate charge-trap “island.” As a result, the charge-trap region of one memory cell is electrically isolated from charge-trap regions in adjacent memory cells. The charge trap region of one memory cell is separated from the charge trap regions of adjacent memory cells by a dielectric structure, such as a silicon oxide film. Alternatively, the charge trap region of a memory cell is separated from the charge trap regions of adjacent memory cells by an air, gas, or vacuum gap.
