    摘要: A method of programming a non-volatile memory device may include performing a first programming operation including applying a program voltage to a memory cell and verifying the memory cell using a first verification voltage. A perturbation pulse may be applied to the memory cell to facilitate thermalization of charges in the memory cell if the memory cell passes the verification using the first verification voltage. The memory cell may be verified using a second verification voltage greater than the first verification voltage after the perturbation pulse is applied.

    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.
