    摘要: A nonvolatile memory device (800) includes a variable resistance nonvolatile memory element (100) and a control circuit (810). The control circuit (810) determines whether a resistance value of the nonvolatile memory element (100) in a high resistance state is equal to or greater than a predetermined threshold value. Moreover, if the resistance value of the nonvolatile memory element (100) in the high resistance state is smaller than the threshold value, the control circuit (810) applies a first voltage (VL1) to the nonvolatile memory element (100) to change a resistance state of the nonvolatile memory element (100) from the high resistance state to the low resistance state. Moreover, if the resistance value of the nonvolatile memory element (100) in the high resistance state is equal to or greater than the threshold value, the control circuit (810) applies to the nonvolatile memory element (100) a second voltage (VL2) an absolute value of which is smaller an absolute value of the first voltage (VL1) to change the resistance state of the nonvolatile memory element (100) from the high resistance state to the low resistance state.

    摘要: Each of memory cells (MC) includes one transistor and one resistance variable element. The transistor includes a first main terminal, a second main terminal and a control terminal. The resistance variable element includes a first electrode, a second electrode and a resistance variable layer provided between the first electrode and the second electrode. A first main terminal of one of two adjacent memory cells is connected to a second main terminal of the other memory cell, to form a series path (SP) sequentially connecting main terminals of the plurality of memory cells in series. Each of the memory cells is configured such that the control terminal is a part of a first wire (WL) associated with the memory cell or is connected to the first wire associated with the memory cell, the second electrode is a part of a second wire (SL) associated with the memory cell or is connected to the second wire associated with the memory cell; and the first electrode is a part of a series path (SP) associated with the memory cell or is connected to the series path associated with the memory cell.
