Abstract:
A programmable charge-storage transistor comprises channel material, insulative charge-passage material, charge-storage material, a control gate, and charge-blocking material between the charge-storage material and the control gate. The charge-blocking material comprises a non-ferroelectric insulator material and a ferroelectric insulator material. Arrays of elevationally-extending strings of memory cells of memory cells are disclosed, including methods of forming such. Other embodiments, including method, are disclosed.

Claim (Index 31):
A method of forming an array of elevationally-extending strings of memory cells, the method comprising:\n forming a stack comprising vertically-alternating tiers of different composition first and second materials, the first material being insulative; forming elevationally-extending channel openings into the alternating tiers; forming first charge-blocking insulator material in the channel openings elevationally along the alternating tiers; forming charge-storage material in the channel openings elevationally along the alternating tiers and the first charge-blocking insulator material; forming insulative charge-passage material in the channel openings elevationally along the alternating tiers and the charge-storage material; forming transistor channel material in the channel openings elevationally along the alternating tiers and the insulative charge-passage material; removing at least some of the second material from the stack; forming second charge-blocking insulator material laterally proximate the first charge-blocking insulator material, the second charge-blocking insulator material being of different composition from that of the first charge-blocking insulator material, one of the first charge-blocking insulator material or the second charge-blocking insulator material comprising a non-ferroelectric insulator material, the other of the first charge-blocking insulator material or the second charge-blocking insulator material comprising a ferroelectric insulator material; and forming control-gate material laterally over the second charge-blocking insulator material, the control-gate material having terminal ends corresponding to control-gate regions of individual memory cells.
