  • Publication number: 20230073372
    Abstract: A microelectronic device comprises a stack structure overlying a source tier. The stack structure comprising a vertically alternating sequence of conductive structures and insulative structures arranged in tiers. The microelectronic device comprises a staircase structure within the stack structure and having steps comprising lateral edges of the tiers, support structures vertically extending through the stack structure and within a horizontal area of the staircase structure, and conductive contacts vertically extending through the stack structure and horizontally neighboring the support structures within the horizontal area of the staircase structure. Each of the conductive contacts has a horizontally projecting portion in contact with one of the conductive structures of the stack structure at one of the steps of the staircase structure. Related memory devices, electronic systems, and methods of forming the microelectronic devices are also described.

  • Patent number: 9136471
    Abstract: 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.
