    Abstract: Some embodiments include an integrated structure having a first opening extending through a stack of alternating insulative levels and conductive levels. A nitride structure is within the first opening and narrows the first opening to form a second opening. Detectable oxide is between the nitride structure and one or more of the conductive levels. 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. A first opening extends through the vertically-stacked levels to the conductive material and has opposing sidewalls along a cross-section. Nitride liners are along the sidewalls of the first opening. Detectable oxide is between at least one of the nitride liners and one or more of the vertically-stacked conductive levels. Some embodiments include methods for forming integrated structures.

    Abstract: Various embodiments include methods of forming memory cells. In one embodiment, a first dielectric material and a second dielectric material are formed on a substrate. A conductive material is formed between the first dielectric material and the second dielectric material. An opening is formed through the first dielectric material, the second dielectric material, and the conductive material. The conductive material is recessed laterally from the opening to form a recessed control gate and to expose portions of the first dielectric material and the second dielectric material. Portions of a third dielectric material are formed over the exposed portions of the first dielectric material and the second dielectric material and a charge storage element is formed between the portions of the third dielectric material and adjacent to the recessed control gate. Portions of the third dielectric material are substantially removed. Additional methods, as well as apparatuses, are disclosed.
