  • Patent number: 11183236
    Abstract: A memory device that includes at least one memory cell is introduced. Each of the at least one memory cell is coupled to a bit line and a word line. Each of the at least one memory cell includes a memory element and a selector element, in which the memory element is configured to store data of the at least one memory cell.

  • Patent number: 11177435
    Abstract: A via-level dielectric material layer is formed over a first dielectric material layer embedding a first conductive structure. A via cavity is formed through the via-level dielectric material layer. A least one straight sidewall vertically extends from a closed upper periphery of the via cavity at a top surface of the via-level dielectric material layer to a closed lower periphery of the via cavity that is adjoined to a top surface of the first conductive structure. A pillar stack structure is formed in the via cavity by sequentially forming a set of material portions containing a lower pillar structure and an upper pillar structure. The lower pillar structure and the upper pillar structure include a selector material pillar and a memory material pillar. A second conductive structure may be formed on a top surface of the pillar stack structure. The pillar stack structure may be used in an array configuration.
