Methods, systems, and devices for self-selecting memory with horizontal access lines are described. A memory array may include first and second access lines extending in different directions. For example, a first access line may extend in a first direction, and a second access line may extend in a second direction. At each intersection, a plurality of memory cells may exist, and each plurality of memory cells may be in contact with a self-selecting material. Further, a dielectric material may be positioned between a first plurality of memory cells and a second plurality of memory cells in at least one direction. each cell group (e.g., a first and second plurality of memory cells) may be in contact with one of the first access lines and second access lines, respectively.
