Abstract:
Some embodiments include a memory cell which has, in the following order; a control gate, charge-blocking material, charge-trapping material, a first oxide, a charge-passage structure, a second oxide, and channel material. The charge-passage structure has a central region sandwiched between first and second regions. The central region has a lower probability of trapping charges and/or a lower rate of trapping charges than the first and second regions. Some embodiments include an integrated structure having a vertical stack of alternating conductive levels and insulative levels, and having a charge-passage structure extending vertically along the vertical stack. Some embodiments include a NAND memory array having a vertical stack of alternating insulative levels and wordline levels, and having a charge-passage structure extending vertically along the vertical stack.

Claim (Index 13):
A NAND memory array, comprising:\n a vertical stack of alternating insulative levels and wordline levels;; charge-blocking material extending vertically along the vertical stack; charge-storage material extending vertically along the charge-blocking material; and a charge-passage structure extending and consisting of a central region sandwiched between first and second regions, each of the first region, the second region and the central region containing nitrogen, the charge-passage structure having at least one external sidewali surface that consists of silicon nitride, wherein an oxygen gradient extends from one of the external sidewall surfaces at least partially through the charge-passage structure.
