Abstract
Some embodiments include a NAND 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 is spaced from the control gate regions by charge-blocking material. The charge-trapping material along vertically adjacent wordline levels is spaced by intervening regions through which charge migration is impeded. Channel material extends vertically along the stack and is spaced from the charge-trapping material by charge-tunneling material. Some embodiments include methods of forming NAND memory arrays.
