摘要: A non-volatile data storage device comprises pairs of immediately adjacent and isolated-from-one-another local bit lines that are independently driven by respective and vertically oriented bit line selector devices. The isolation between the immediately adjacent and isolated-from-one-another local bit lines also isolates from one another respective memory cells of the non-volatile data storage device such that leakage currents cannot flow from memory cells connected to a first of the immediately adjacent and isolated-from-one-another local bit lines to memory cells connected to the second of the pair of immediately adjacent and isolated-from-one-another local bit lines. A method programming a desire one of the memory cells includes applying boosting voltages to word lines adjacent to the bit line of the desired memory cell while not applying boosting voltages to word lines adjacent to the other bit line of the pair.

摘要: A 3D nonvolatile memory has memory elements arranged in a three-dimensional pattern with a plurality of memory layers stacked over a semiconductor substrate. It has a 2D array of vertical bit lines and a plurality of staircase word lines. Each staircase word line has a series of alternating segments and risers and traverses the plurality of memory layers with a segment in each memory layer. The plurality of staircase word lines have their segments lined up to form a 2D array of stacks of segments. Riser for a pair of segments from each adjacent stacks at different memory layers is provided by a conductive sidewall layer of a stairwell disposed between the adjacent stacks. Multiple insulated conductive sidewall layers provide multiple risers for the adjacent stacks. Layer-by-layer stairwell excavation and sidewall processes between adjacent stacks create risers for different pairs of segments between stacks to form the staircase word lines.

摘要: A method of forming a non-volatile resistive oxide memory cell includes forming a first conductive electrode of the memory cell as part of a substrate. Metal oxide-comprising material is formed over the first conductive electrode. Etch stop material is deposited over the metal oxide-comprising material. Conductive material is deposited over the etch stop material. A second conductive electrode of the memory cell which comprises the conductive material received is formed over the etch stop material. Such includes etching through the conductive material to stop relative to the etch stop material and forming the non-volatile resistive oxide memory cell to comprise the first and second conductive electrodes having both the metal oxide-comprising material and the etch stop material therebetween. Other implementations are contemplated.
