    Abstract: 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 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.

    Abstract: Some embodiments include an integrated assembly having a channel-material-pillar extending vertically through a stack of alternating conductive levels and insulative levels. The channel-material-pillar includes a first semiconductor material. A second semiconductor material is directly against an upper region of the channel-material-pillar. The second semiconductor material has a higher dopant concentration than the first semiconductor material and joins to the first semiconductor along an abrupt interfacial region such that there is little to no mixing of dopant from the second semiconductor material into the first semiconductor material. Some embodiments include methods of forming integrated assemblies.

    Abstract: Some embodiments include a memory cell having a non-ohmic device between a transistor source/drain region and a capacitor. Some embodiments include a memory cell having a transistor with a first source/drain region, a second source/drain region, and a channel region between the first and second source/drain regions. A capacitor is electrically coupled to the second source/drain region through a non-ohmic device. The non-ohmic device includes a non-ohmic-device-material which changes conductivity in response to an electrical property along the channel region. The non-ohmic-device-material has a high-resistivity-mode when the electrical property along the channel region is below a threshold level, and transitions to a low-resistivity-mode when the electrical property along the channel region meets or exceeds the threshold level. Some embodiments include a memory array.

    Abstract: A method of forming a microelectronic device comprises forming a stack structure comprising vertically alternating insulating structures and conductive structures arranged in tiers. Each of the tiers individually comprises one of the insulating structures and one of the conductive structures. A sacrificial material is formed over the stack structure and pillar structures are formed to extend vertically through the stack structure and the sacrificial material. The method comprises forming conductive plug structures within upper portions of the pillar structures, forming slots extending vertically through the stack structure and the sacrificial material, at least partially removing the sacrificial material to form openings horizontally interposed between the conductive plug structures, and forming a low-K dielectric material within the openings. Microelectronic devices, memory devices, and electronic systems are also described.
