Nonvolatile memory device, method of operating nonvolatile memory device and storage device including the same

Abstract

A nonvolatile memory device includes a memory cell array and a control circuit. The memory cell array includes a plurality of memory blocks, each including a plurality memory cells coupled to word-lines respectively, and the word-lines are stacked vertically on a substrate. The control circuit divides a first memory block of the plurality of memory blocks into a partial bad region and a partial normal region based on error information of an uncorrectable error of the first memory block which is designated as a bad block. The control circuit performs a memory operation on the partial normal region by applying a first bias condition to the partial bad region and by applying a second bias condition to the partial normal region, based on a command and an address, and the first bias condition is different from the second bias condition.
