Integrated assemblies having vertically-spaced channel material segments, and methods of forming integrated assemblies

Last updated:

Abstract:

Some embodiments include a NAND memory array having a vertical stack of alternating insulative levels and wordline levels. The wordline levels have primary regions of a first vertical thickness, and have terminal projections of a second vertical thickness which is greater than the first vertical thickness. The terminal projections include control gate regions. Charge-blocking regions are adjacent the control gate regions, and are vertically spaced from one another. Charge-storage regions are adjacent the charge-blocking regions and are vertically spaced from one another. Gate-dielectric material is adjacent the charge-storage regions. Channel material is adjacent the gate dielectric material. Some embodiments included methods of forming integrated assemblies.
