Non-volatile memory device, erasing method of a nonvolatile memory device, a method of operating a nonvolatile memory device, a memory system including a nonvolatile memory device, a method of operating a memory system, a memory card including a nonvolatile memory device, and solid-state drive

摘要

An erase system and method of a nonvolatile memory device includes supplying an erase voltage to a plurality of memory cells of a nonvolatile memory, performing a read operation with a read voltage to word lines of the plurality of memory cells, and performing an erase verification operation with an erase verification voltage to at least one of the word lines of the plurality of memory cells, the erase verification voltage lower than the read voltage.
