    摘要: A nonvolatile memory device includes resistive memory devices in a three-dimensional structure. A block select circuit generates a block select signal for selecting a memory block. In response to the block select signal, local word line selection units connected to each memory block connect global word lines connected to a word line decoder and local word lines, and local bit line selection units connected to each memory block connect global bit lines connected to a sense amplifier and local bit lines. Each memory block includes local word lines which extend in a first direction and are stacked in a second direction perpendicular to the first direction on a second plane perpendicular to a first plane. Local bit lines extend in the second direction to cross local word lines. Memory cells are formed at cross-points where local word lines and local bit lines cross one another.

    摘要: Provided is a resistance random access memory device and a method of fabricating, the same. The method includes forming a bit-line stack in which a plurality of local bit-lines are vertically stacked on a substrate, forming a word-line including a plurality of local word-lines that extend in a vertical direction toward a side of the bit-line stack and a connection line that extends in a horizontal direction to connect the plurality of local word-lines with one another, and forming a resistance memory thin film between the bit-line stack and the word-line. The present inventive concept can realize a highly dense memory array with 3D cross-point architecture by simplified processes.

    摘要: Methods of forming phase-changeable memory devices include techniques to inhibit void formation in phase-changeable materials in order to increase device reliability. These techniques to inhibit void formation use an electrically insulating growth-inhibiting layer to guide the formation of a phase-changeable material region within a memory cell (e.g., PRAM cell). In particular, methods of forming an integrated circuit memory device include forming an interlayer insulating layer having an opening therein, on a substrate, and then lining sidewalls of the opening with a seed layer (i.e., growth-enhancing layer) that supports growth of a phase-changeable material thereon. An electrically insulating growth-inhibiting layer is then selectively formed on a portion of the interlayer insulating layer surrounding the opening. The formation of the growth-inhibiting layer is followed by a step to selectively grow a phase-changeable material region in the opening, but not on the growth-inhibiting layer.
