    摘要: A charge trap memory device may include a tunnel insulating layer formed on a substrate. A charge trap layer may be formed on the tunnel insulating layer, wherein the charge trap layer is a higher-k dielectric insulating layer doped with one or more transition metals. The tunneling insulating layer may be relatively non-reactive with respect to metals in the charge trap layer. The tunneling insulating layer may also reduce or prevent metals in the charge trap layer from diffusing into the substrate.

    摘要: A method of programming a nonvolatile memory device may include applying a program voltage to a memory cell. A supplementary pulse may be applied to the memory cell to facilitate thermalization of charges after the application of the program voltage. A recovery voltage may be applied to the memory cell after the application of the supplementary pulse. A program state of the memory cell may be verified using a verification voltage after the application of the recovery voltage.

    摘要: Example embodiments relate to nonvolatile semiconductor memory devices using an electric charge storing layer as a storage node and fabrication methods thereof. An electric charge trap type nonvolatile memory device may include a tunneling film, an electric charge storing layer, a blocking insulation film, and a gate electrode. The blocking insulation film may be an aluminum oxide having an energy band gap larger than that of a γ-phase aluminum oxide film. An α-phase crystalline aluminum oxide film as a blocking insulation film may have an energy band gap of about 7.0 eV or more along with fewer defects. The crystalline aluminum oxide film may be formed by providing a source film (e.g., AlF3 film) on or within a preliminary blocking insulation film (e.g., amorphous aluminum oxide film) and performing a heat treatment. Alternatively, an aluminum compound (e.g., AlF3) may be introduced into the preliminary blocking insulation film by other diffusion methods or ion implantation. Accordingly, the ability of the memory device to maintain electric charges may be improved, the operating voltage for programming and erasing may be lowered, and the operating speed may be increased.
