Abstract
A memory device includes an alternating stack of insulating layers and control gate layers, a memory opening vertically extending through the alternating stack, and a memory opening fill structure containing a memory film and a vertical semiconductor channel located within the memory opening. The memory film contains a resonant tunneling barrier stack, a semiconductor barrier layer, and a memory material layer located between the resonant tunneling barrier stack and the semiconductor barrier layer.
