Abstract
Three-dimensional memory cells and methods of making and using the memory cells are discussed generally herein. In one or more embodiments, a three-dimensional vertical memory can include a memory stack. Such a memory stack can include memory cells and a dielectric between adjacent memory cells, each memory cell including a control gate and a charge storage structure. The memory cell can further include a barrier material between the charge storage structure and the control gate, the charge storage structure and the barrier material having a substantially equal dimension.
