    Abstract: Three-dimensional (3D) nonvolatile memory devices include a substrate having a well region of second conductivity type (e.g., P-type) therein and a common source region of first conductivity type (e.g., N-type) on the well region. A recess extends partially (or completely) through the common source region. A vertical stack of nonvolatile memory cells on the substrate includes a vertical stack of spaced-apart gate electrodes and a vertical active region, which extends on sidewalls of the vertical stack of spaced-apart gate electrodes and on a sidewall of the recess. Gate dielectric layers extend between respective ones of the vertical stack of spaced-apart gate electrodes and the vertical active region. The gate dielectric layers may include a composite of a tunnel insulating layer, a charge storage layer, a relatively high bandgap barrier dielectric layer and a blocking insulating layer having a relatively high dielectric strength.

    Abstract: Three-dimensional semiconductor devices are provided. The three-dimensional semiconductor device includes a substrate, a buffer layer on the substrate. The buffer layer includes a material having an etching selectivity relative to that of the substrate. A multi-layer stack including alternating insulation patterns and conductive patterns is provided on the buffer layer opposite the substrate. One or more active patterns respectively extend through the alternating insulation patterns and conductive patterns of the multi-layer stack and into the buffer layer. Related fabrication methods are also discussed.

    Abstract: A nonvolatile memory device and a method of programming the same. The nonvolatile memory device includes a memory cell array including a plurality of memory cells and a program control logic circuit controlling the memory cell array. The program control logic circuit programs a first memory cell so that the threshold voltage of the first memory cell corresponding to data of erasure state is higher than the threshold voltage of a second memory cell corresponding to data of program state, in the memory cell array. The nonvolatile memory device controlled in this manner can provide higher reliability.
