摘要: The present invention provides nonvolatile semiconductor memory devices which operate with low power consumption. In a nonvolatile semiconductor memory device, a plurality of nonvolatile memory elements are connected in series. The plurality of nonvolatile memory elements include a semiconductor layer including a channel forming region and a control gate provided to overlap with the channel forming region. Operations of write, erase, a first read, and a second read in a verify operation of data to the nonvolatile memory elements, are conducted by changing voltage to the control gates of the nonvolatile memory elements. The second read in the verify operation after erase operation is conducted by changing only one of a potential of the control gate of a nonvolatile memory element which are selected from the plurality of nonvolatile memory elements, and as the potential, a potential different from a potential of the first read is used.

摘要: To provide a method of releasing charges which have been injected into charge accumulating layers of nonvolatile memory elements without using a substrate terminal such as a p well or an n well, as a method for deleting data from a NAND-type nonvolatile memory. In the method for deleting data from the NAND-type nonvolatile memory, charges stored in a charge accumulating layer of a first nonvolatile memory element are released by applying a first potential to a bit line and a source line, a second potential to a control gate of the first nonvolatile memory element, and a third potential which is different from the second potential to a control gate of a second nonvolatile memory element.
