Abstract
Disclosed is a method reading memory device information from a nonvolatile memory device having a three-dimensional (3D) memory cell array including an original plane storing data associated with the information in a first group of memory cells and a replica plane storing the data in replica in a second group of memory cells. The method applies a selection read voltage to a selected word line connected to first and second groups of memory cells while applying a non-selection read voltage to other word lines, and simultaneously reading first data from the first group of memory cells and second data from the second group of memory cells.
