摘要:
Methods, systems, and devices for plate node configurations and operations for a memory array are described. A single plate node of a memory array may be coupled to multiple rows or columns of memory cells (e.g., ferroelectric memory cells) in a deck of memory cells. The single plate node may perform the functions of multiple plate nodes. The number of contacts to couple the single plate node to the substrate may be less than the number of contacts to couple multiple plate nodes to the substrate. Connectors or sockets in a memory array with a single plate node may define a size that is less than a size of the connectors or sockets with multiple plate nodes. In some examples, a single plate node of the memory array may be coupled to multiple lines of a memory cells in multiple decks of memory cells.

A method of forming an array comprising pairs of vertically opposed capacitors comprises forming a conductive lining in individual capacitor openings in support material. An elevational mid-portion of individual of the conductive linings is removed to form an upper capacitor electrode lining and a lower capacitor electrode lining that are elevationally separate and spaced from one another in the individual capacitor openings. A capacitor insulator is formed laterally outward of the upper and lower capacitor electrode linings. Conductive material is formed laterally outward of the capacitor insulator to comprise a shared capacitor electrode that is shared by vertically opposed capacitors in individual of the pairs of vertically opposed capacitors. Other methods and structure independent of method of manufacture are disclosed.
