20110222339 | NONVOLATILE MEMORY DEVICE FOR REDUCING INTERFERENCE BETWEEN WORD LINES AND OPERATION METHOD THEREOF - Provided are a nonvolatile memory device and a method of operating the same. The nonvolatile memory device in accordance with an embodiment of the inventive concept may include a string select line; a ground select line; a dummy word line adjacent to the ground select line; a first word line adjacent to the dummy word line; and a second word line disposed between the string select line and the first word line. The nonvolatile memory device is configured to apply a voltage to the dummy word line. When programming a memory cell connected to the first word line, a first dummy word line voltage lower than a voltage applied to the second word line is applied to the dummy word line. When programming a memory cell connected to the second word line, a second dummy word line voltage between a voltage applied to the first word line and the first dummy word line voltage is applied to the dummy word line. Accordingly, when a program operation is performed, a charge loss of a memory cell connected to a word line adjacent to a dummy word line can be reduced by changing a voltage applied to the dummy word line according to a select word line. | 09-15-2011 |
