Abstract
Some embodiments include a NAND memory array having a vertical stack of alternating insulative levels and conductive levels. The conductive levels include control gate regions and include second regions proximate to the control gate regions. High-k dielectric structures are directly against the control gate regions and extend entirely across the insulative levels. Charge-blocking material is adjacent to the high-k dielectric structures. Charge-storage material is adjacent to the charge-blocking material. The charge-storage material is configured as segments which are vertically stacked one atop another, and which are vertically spaced from one another. Gate-dielectric material is adjacent to the charge-storage material. Channel material extends vertically along the stack and is adjacent to the gate-dielectric material. Some embodiments include integrated assemblies, and methods of forming integrated assemblies.
