    摘要: A memristor device includes a first electrode, a second electrode, and a memristor layer disposed between the first electrode and the second electrode. The memristor layer is formed of a metal oxide. The memristor layer includes a plurality of regions that extend between the first electrode and the second electrode. The plurality of regions of the memristor layer are created with different concentrations of oxygen before electrical operation, and, during electrical operation, a voltage-conductance characteristic of the memristor device is controlled based on the different concentrations of oxygen of the plurality of regions. The controlling of the voltage-conductance characteristic includes increasing or decreasing the conductance of the memristor device toward a target conductance at a specific voltage.

    摘要: Memory devices with controlled wordline ramp rates and associated systems and methods are disclosed herein. In one embodiment, a memory device includes at least one voltage regulator and a plurality of wordlines. The memory device is configured, during a programming operation of the memory region, to ramp a selected wordline to a desired programming voltage while ramping one or more adjacent, unselected wordlines electrically coupled to the selected wordline to desired inhibit voltage(s) using the at least one voltage regulator. In some embodiments, the memory device ramps the selected wordline and the one or more adjacent, unselected wordlines such that the one or more adjacent, unselected wordlines reach the desired inhibit voltage(s) when the selected wordline reaches the desired programming voltage. In these and other embodiments, the memory device ramps the selected wordline to the desired programming voltage without floating the selected wordline.

    摘要: A memory device includes first electrode layers stacked in a first direction, a first semiconductor layer piercing the first electrode layers in a first direction, a first insulating film surrounding the first semiconductor layer, and a semiconductor base connected to the first semiconductor layer. The first insulating film includes a first film, a second film, and a third film provided in order in a second direction from the first semiconductor layer toward one of first electrode layers. Spacing in the first direction between the second film and the semiconductor base is wider than a film thickness of the third film in the second direction. A minimum width of an outer perimeter of the first semiconductor layer is substantially the same as a width of an outer perimeter at a portion of the first semiconductor layer piercing the most proximal first electrode layer.
