Nonvolatile memory device, driving method thereof, and memory system having the same

摘要

A nonvolatile memory device (NVM), memory system and apparatus include control logic configured to perform a method of applying negative voltage on a selected wordline of the NVM. During a first time a first high voltage level is applied to the channel of a transistor of a address decoder and a ground voltage is applied to the well of the transistor. And, during a second time a second high voltage level is applied to the channel of the transistor, and within the second time interval a first negative voltage is applied to the well of the transistor. The first high voltage level is higher than the second high voltage level, and a voltage applied on the selected wordline is negative within the second time interval.
