A method used in forming a memory array comprises forming a stack comprising vertically-alternating insulative tiers and conductive tiers. Channel-material strings of memory-cell strings extend through the insulative and conductive tiers. Conductive vias are formed above and individually electrically coupled to individual of the channel-material strings. Insulating material is laterally-between immediately-adjacent of the conductive vias. At least some of the insulating material is vertically removed to form an upwardly-open void-space that is circumferentially about multiple of the conductive vias. Insulative material is formed laterally-between the immediately-adjacent conductive vias to form a covered void-space from the upwardly-open void-space. Digitlines are formed above that are individually electrically coupled to a plurality of individual of the conductive vias there-below. Other embodiments, including structure independent of method, are disclosed.
