Abstract
A memory array comprising strings of memory cells comprises laterally-spaced memory blocks individually comprising a vertical stack comprising alternating insulative tiers and conductive tiers directly above a conductor tier. Strings of memory cells comprise channel-material strings that extend through the insulative tiers and the conductive tiers. The channel-material strings directly electrically couple with conductor material of the conductor tier by conductive material of a lowest of the conductive tiers. Insulating material of the insulative tier that is immediately-directly above the lowest conductive tier is directly against a top of the conductive material of the lowest conductive tier. The insulating material comprises at least one of aluminum oxide, hafnium oxide, zirconium oxide, and carbon-doped insulative material. Other embodiments, including method, are disclosed.
