Abstract: Some embodiments include a method of forming stacked memory decks. A first deck has first memory cells arranged in first tiers disposed one atop another, and has a first channel-material pillar extending through the first tiers. An inter-deck structure is over the first deck. The inter-deck structure includes an insulative expanse, and a region extending through the insulative expanse and directly over the first channel-material pillar. The region includes an etch-stop structure. A second deck is formed over the inter-deck structure. The second deck has second memory cells arranged in second tiers disposed one atop another. An opening is formed to extend through the second tiers and to the etch-stop structure. The opening is subsequently extended through the etch-stop structure. A second channel-material pillar is formed within the opening and is coupled to the first channel-material pillar. Some embodiments include integrated assemblies.

Abstract: Integrated circuitry has an array circuitry region having a repeating array of electronic components. An adjacent circuitry region is immediately laterally adjacent to and contacts one elongated major peripheral side of the array circuitry region. The adjacent circuitry region is distinct in structure from the array circuitry region where contacting the array circuitry region and distinct in operation from the array circuitry region. The array circuitry region and the adjacent circuitry region have a respective longitudinally non-linear edge at an interface relative one another along the one elongated major peripheral side of the array circuitry region. Other embodiments are disclosed.

Abstract: Some embodiments include an integrated assembly with a semiconductor channel material having a boundary region where a more-heavily-doped region interfaces with a less-heavily-doped region. The more-heavily-doped region and the less-heavily-doped region have the same majority carriers. The integrated assembly includes a gating structure adjacent the semiconductor channel material and having a gating region and an interconnecting region of a common and continuous material. The gating region has a length extending along a segment of the more-heavily-doped region, a segment of the less-heavily-doped region, and the boundary region. The interconnecting region extends laterally outward from the gating region on a side opposite the semiconductor channel region, and is narrower than the length of the gating region. Some embodiments include methods of forming integrated assemblies.

Abstract: Some embodiments include an integrated structure having a vertical stack of alternating insulative levels and conductive levels. The conductive levels include primary regions of a first vertical thickness, and terminal projections of a second vertical thickness which is greater than the first vertical thickness. Charge-blocking material is adjacent the terminal projections. Charge-storage material is adjacent the charge-blocking material. Gate-dielectric material is adjacent the charge-storage material. Channel material is adjacent the gate-dielectric material. Some embodiments include NAND memory arrays. Some embodiments include methods of forming integrated structures.

Abstract: Some embodiments include an integrated structure having a conductive material, a select device gate material over the conductive material, and vertically-stacked conductive levels over the select device gate material. Vertically-extending monolithic channel material is adjacent the select device gate material and the conductive levels. The monolithic channel material contains a lower segment adjacent the select device gate material and an upper segment adjacent the conductive levels. A first vertically-extending region is between the lower segment of the monolithic channel material and the select device gate material. The first vertically-extending region contains a first material. A second vertically-extending region is between the upper segment of the monolithic channel material and the conductive levels. The second vertically-extending region contains a material which is different in composition from the first material.

Abstract: Some embodiments include a memory array which has a vertical stack of alternating insulative levels and wordline levels. The wordline levels have terminal ends corresponding to control gate regions. Charge-trapping material is along the control gate regions of the wordline levels and not along the insulative levels. The charge-trapping material is spaced from the control gate regions by charge-blocking material. Channel material extends vertically along the stack and is laterally spaced from the charge-trapping material by dielectric material. Some embodiments include methods of forming NAND memory arrays.
