OPERATING METHOD OF NONVOLATILE MEMORY DEVICE, AND NONVOLATILE MEMORY DEVICE IMPLEMENTING THE SAME

摘要

PURPOSE: An operating method of a nonvolatile memory device, and the nonvolatile memory device implementing the same are provided to improve the efficiency of programming and reading data by driving two word lines through one plane. CONSTITUTION: A first plane(310) comprises a first memory block group(310a) and a second memory block group(310b). A second plane(330) comprises a third memory block group(330a) and a fourth memory block group(330b). A controller(100) controls a voltage generator to generate a bias voltage from the voltage generator. The controller controls the voltage generator, a first page buffer, a second page buffer, a third page buffer, and a fourth page buffer. The first - fourth block decoding units(510-540) respectively corresponds to the first-fourth memory block group.
