US Patent 11856791 Nonvolatile storage device

A nonvolatile storage device includes first interconnections extending in a first direction and second interconnections extending in a second direction intersecting the first direction. Memory cells are formed at intersections between first and second interconnections. Each memory cell includes a resistance change element and a selector. In the arrangement of memory cells, all memory cells that are connected to any particular first interconnection are aligned along that first interconnection, and all memory cells connected to any particular second interconnection are alternately staggered in the first direction across a width of that second interconnection.
