    摘要: A semiconductor memory device includes a stacked structure including a plurality of wordline structures sequentially stacked that each include: a plurality of wordlines with sidewalls and extending in a first direction on the substrate, and a connecting pad extending in a second direction on the substrate and being connected in common to the plurality of wordlines. A plurality of interconnections at a height over the substrate are connected to the connecting pads of the wordline structures, respectively. The device further includes bitlines substantially vertical to a top surface of the substrate and crossing one of the sidewalls of the plurality of wordlines, and memory elements between the bitlines and the plurality of wordlines, respectively. A length of the connecting pad in the second direction is substantially equal to a product of a minimum pitch between the interconnections and a stack number of one of the plurality of wordlines.

    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.
