Original Abstract Submitted
Methods, systems, and devices for access circuitry structures for three-dimensional (3D) memory arrays are described. A memory device may include levels of memory cells over a substrate. To support accessing memory cells at respective levels, the memory device may include a conductive pillar extending through the levels of memory cells and coupled with one or more memory cells at respective levels of memory cells. The memory device may include a bit line and a contact that is configured to couple the bit line with the conductive pillar. The conductive pillar may be formed such that it extends into a portion of the contact, and a contact resistance between the conductive pillar and the bit line may be based on the conductive pillar extending into the portion of the contact.
