    摘要: In a memory cell array, memory cells each including a variable resistance element are arranged at crossing portions between a plurality of first wiring and a plurality of second wirings. A control circuit executes a set operation, a reset operation, and a training operation. In the set operation, a set pulse is applied to the variable resistance element to change the variable resistance element from a high resistance state to a low resistance state. In the reset operation, a reset pulse having an opposite polarity to the polarity of the set pulse is applied to the variable resistance element to change the variable resistance element from the low resistance state to the high resistance state. In the training operation, the set pulse and the reset pulse are continuously applied to the variable resistance element.

    摘要: Nonvolatile semiconductor memory device of an embodiment includes: a memory cell array including a plurality of first and second lines intersecting each other and plural memory cells provided at intersections of the first and second lines and having data written and erased upon application of voltages of the same polarity; and a writing circuit configured to select first and second lines and supply a set or reset pulse to the memory cell through the selected first and second lines. In an erase operation, the writing circuit repeatedly supplies the reset pulse to a selected memory cell until data is erased, by increasing or decreasing voltage level and voltage application time of the reset pulse within a reset region. The reset region, or an aggregate of combinations of voltage level and voltage application time of the reset pulse, is a region where voltage level and voltage application time are negatively correlated.
