    摘要: A non-volatile memory with a self-aligned RRAM element includes a lower electrode element, generally planar in form, having an inner contact surface; an upper electrode element, spaced from the lower electrode element; a containment structure extends between the upper electrode element and the lower electrode element, with a sidewall spacer element having a generally funnel-shaped central cavity with a central aperture; and a spandrel element positioned between the sidewall spacer element and the lower electrode. A RRAM element extends between the lower electrode element and the upper electrode, occupying at least a portion of the sidewall spacer element central cavity and projecting from the sidewall spacer terminal edge toward and making contact with the lower electrode. In this manner, the spandrel element inner surface is spaced from the RRAM element to define a thermal isolation cell adjacent the RRAM element.

    摘要: A memory cell device, having a memory material switchable between electrical property states by the application of energy, comprises an electrode, a separation layer against an electrode surface, a hole in the separation layer, a second material in the hole defining a void having a downwardly and inwardly tapering void region. A memory material is in the void region in electrical contact with the electrode surface. A second electrode is in electrical contact with the memory material. Energy passing between the first and second electrodes is concentrated within the memory material so to facilitate changing an electrical property state of the memory material. The memory material may comprise a phase change material. The second material may comprise a high density plasma-deposited material. A method for making a memory cell device is also discussed.
