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.

Claim (Index 6):
A method of forming a NAND memory array, comprising:\n forming a vertical stack of alternating first and second levels; the first levels comprising first material, and the second levels comprising second material; the first and second levels having exposed surfaces along an opening extending through the first and second levels; selectively forming charge-trapping material along the exposed surfaces of the second levels relative to the exposed surfaces of the first levels, the charge-trapping material being entirely within the opening; forming charge-tunneling material extending vertically along the first and second levels, and spaced from the second levels by the charge-trapping material; forming channel material within the opening extending vertically along the charge-tunneling material; removing the second material to leave voids; and forming conductive levels within the voids; the conductive levels being wordline levels of the NAND memory array, the wordline levels comprising a conductive core material and a conductive liner material lining the conductive core material and having terminal ends along the opening corresponding to control gate regions.
