    摘要: Some embodiments include semiconductor constructions having an electrically conductive interconnect with an upper surface, and having an electrically conductive structure over the interconnect. The structure includes a horizontal first portion along the upper surface and a non-horizontal second portion joined to the first portion at a corner. The second portion has an upper edge. The upper edge is offset relative to the upper surface of the interconnect so that the upper edge is not directly over said upper surface. Some embodiments include memory arrays.

    摘要: Resistive memory cells having a plurality of heaters and methods of operating and forming the same are described herein. As an example, a resistive memory cell may include a resistance variable material located between a first electrode and a second electrode, a first heater coupled to a first portion of the resistance variable material, a second heater coupled to a second portion of the resistance variable material, a third heater coupled to a third portion of resistance variable material, and a conductive material coupled to the first, second, and third heaters.

    摘要: A resistive random access memory array may be formed on the same substrate with a fuse array. The random access memory and the fuse array may use the same active material. For example, both the fuse array and the memory array may use a chalcogenide material as the active switching material. The main array may use a pattern of perpendicular sets of trench isolations and the fuse array may only use one set of parallel trench isolations. As a result, the fuse array may have a conductive line extending continuously between adjacent trench isolations. In some embodiments, this continuous line may reduce the resistance of the conductive path through the fuses.

    摘要: Memory cells having heaters with angled sidewalls and methods of forming the same are described herein. As an example, a method of forming an array of resistive memory cells can include forming a first resistive memory cell having a first heater element angled with respect to a vertical plane, forming a second resistive memory cell adjacent to the first resistive memory cell and having a second heater element angled with respect to the vertical plane and toward the first heater, and forming a third resistive memory cell adjacent to the first resistive memory cell and having a third heater element angled with respect to the vertical plane and away from the first heater element.
