• This abstract for appeared for patent application number 18209983 Titled 'NONVOLATILE MEMORY DEVICE'

Simplified Explanation

The abstract describes a nonvolatile memory device that has a substrate with a cell array region. It also has a first gate electrode with an opening on the cell array region. Stacked above the first gate electrode are multiple second gate electrodes, which have convex portions that curve outward towards the substrate. There is also a word line cutting region that cuts through the opening and the convex portions.
