Abstract

An apparatus, a method, and a system. The method includes implementing an erase operation on a deck of a superblock, block or subblock of a three-dimensional (3D) non-volatile memory device to obtain an erased deck; applying a dummy read pulse to one or more wordlines (WLs) of a to-be-read deck of the superblock, block or subblock; and implementing, after application of the dummy read pulse, a read operation on one or more memory cells corresponding to the one or more WLs to read data from the one or more memory cells.
