NONVOLATILE MEMORY DEVICE PROVIDING NEGATIVE VOLTAGE

摘要

Disclosed is a nonvolatile memory device which includes memory blocks, a pre-decoder, and a row decoder. Each of the memory blocks has a plurality of memory cells. The pre-decoder includes a multiplexer and negative level shifters. The multiplexer is configured to generate multiplexing signals in response to address signals. Each of the negative level shifters is configured to generate a converted multiplexing signal corresponding to a respective multiplexing signal by converting a multiplexing signal having a ground voltage into a converted multiplexing signal having a first negative voltage. The row decoder is configured to select at least one of the memory blocks in response to the converted multiplexing signals.
