    • A nonvolatile memory device and methods for operating and fabricating the same are provided to deposit oxide based compound semiconductor layers so as to increase an integration degree of the device with a multiple structure and to divide/operate blocks simultaneously. A nonvolatile memory device(100) comprises at least one oxide based compound semiconductor layer(110), a plurality of assistant gate electrodes(130), a plurality of control gate electrodes(155), and a plurality of charge storage layers(145). The assistant gate electrodes are insulated from the oxide based compound semiconductor layer. The control gate electrodes are insulated from the oxide based compound semiconductor layer. The charge storage layers are placed between the oxide based compound semiconductor layers and the control gate electrodes respectively. A device isolation layer(120) is placed between the oxide based compound semiconductor layers. A substrate electrode(105) is contacted with lower parts of the oxide based compound semiconductor layers.
