Abstract

Example embodiments relate to a bad area managing method of a nonvolatile memory device. The nonvolatile memory device may include a plurality of memory blocks and each block may contain memory layers stacked on a substrate. According to example embodiments, a method includes accessing one of the memory blocks, judging whether the accessed memory block includes at least one memory layer containing a bad memory cell. If a bad memory cell is detected, the method may further include configuring the memory device to treat the at least one memory layer of the accessed memory block as a bad area.
