Abstract: A split-gate non-volatile memory cell is described, including a substrate, a charge-trapping layer on the substrate, a split gate on the charge-trapping layer, and a source/drain in the substrate beside the split gate. The split gate includes at least one split region directly over the charge-trapping layer, and the charge-trapping layer around the split region serves as a coding region. A NAND non-volatile memory array is also described including the above-mentioned split-gate non-volatile memory cells that are arranged in a NAND-type configuration.

Abstract: A nonvolatile memory cell occupying a minimum chip area is provided with a cell structure that includes two or more base materials being programmable by a heat induced chemical reaction to form a layer or layers of alloy. The formation of alloy results in a change in resistance of the cell structure so that one or more programmed states are determined. A semiconductor memory constructed by a large number of the nonvolatile memory cells can be obtained in a compact manner with simple and as few as possible steps. This process vertically stacked layers, and this semiconductor memory is thus easily to be combined with other integrated circuits on a single chip.
