    摘要: A nonvolatile semiconductor storage device according to an embodiment includes a drive circuit. A voltage applied to a dummy wire connected to a first dummy cell adjacent to a memory string is defined as a first dummy wire voltage, a voltage applied to a selection wire connected to a first memory cell adjacent to the first dummy cell is defined as a first selection wire voltage, and a voltage applied to a selection wire connected to a second memory cell adjacent to the first memory cell is defined as a second selection wire voltage. When the second selection wire voltage is lower than the first dummy wire voltage in an erase operation, the drive circuit controls voltages so that a difference between the first dummy wire voltage and the second selection wire voltage is less than a difference between the first dummy wire voltage and the first selection wire voltage.

    摘要: A nonvolatile semiconductor memory device according to one embodiment of the present invention includes: a memory cell array and a control circuit. The control circuit executes a first reading operation and a second reading operation. The first reading operation is an operation of reading a threshold voltage set in the selected memory cell by setting a voltage between a control gate electrode and source of the selected memory cell to a first value. The second reading operation is an operation of reading a threshold voltage set in the selected memory cell by setting a voltage between the control gate electrode and source of the selected memory cell to a second value lower than the first value. When executing the second reading operation, the control circuit keeps a voltage of the control gate electrode of the selected memory cell to 0 or a positive value.

    摘要: A first non-selected word line including a word line adjacent to a selected word line is applied with a first write pass voltage. Furthermore, a second non-selected word line which is a non-selected word line excluding the first non-selected word line is applied with a second write pass voltage smaller than a program voltage. A control circuit, in the write operation, raises the first write pass voltage toward a first target value by executing a voltage raising operation having a first voltage rise width, X times, and raises the second write pass voltage toward a second target value by executing a voltage raising operation having a second voltage rise width, Y times. The first voltage rise width is larger than the second voltage rise width, and X times is fewer than Y times.
