Abstract:
Floating gate memory cells in vertical memory. A control gate is formed between a first tier of dielectric material and a second tier of dielectric material. A floating gate is formed between the first tier of dielectric material and the second tier of dielectric material, wherein the floating gate includes a protrusion extending towards the control gate. A charge blocking structure is formed between the floating gate and the control gate, wherein at least a portion of the charge blocking structure wraps around the protrusion.

Claim (Index 8):
A memory array, comprising:\n multiple strings of memory cells, the memory cells in the string separated by alternating dielectrics separating each memory cell in the string by a respective alternating dielectric from an adjacent memory cell in the string, wherein each memory cell string includes,\n a respective channel material forming a channel for memory cells of the string, and \n wherein each memory cell of a string comprises,\n a control gate extending between first alternating dielectric at a first surface of the memory cell and a second alternating dielectric at a second surface of the memory cell; \n a floating gate extending between the first alternating dielectric and the second alternating dielectric, the floating gate including a first portion and a second portion, \n wherein the first portion has a first dimension along the direction of current flow through the channel material, the first portion contacting each of the first and second alternating dielectrics, \n wherein the second portion extends from the first portion toward the control gate, and \n wherein the second portion has a second dimension along the direction of current flow through the channel material that is less than the first dimension; \n \n a third dielectric between the second portion of the floating gate and the control gate, a portion of the third dielectric extending between the second portion and at least one of the first and second alternating dielectrics; and \n a fourth dielectric between the first portion of the floating gate and the channel material.
