Title:
METHODS OF OPERATING 3D MEMORY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/034091
Kind Code:
A1
Abstract:
Three-dimensional memory device architectures and methods of operating the devices therefore. A method of erasing memory cells of a memory device includes applying a first voltage greater than 10V to a first semiconductor layer of one or more first vertical structures. The method further includes applying a second voltage greater than 10V to a second semiconductor layer of one or more second vertical structures stacked over the one or more first vertical structures. The method also includes grounding each of a plurality of word lines. The plurality of word lines are arranged in an alternating stack with insulating layers over a substrate, and the one or more first vertical structures and the one or more second vertical structures extend through the alternating stack.
