  • Patent number: 9218878
    Abstract: A semiconductor device is provided with the variable resistance element, and a control circuit that controls a resistance state of the variable resistance element by controlling current between a first end and a second end of the variable resistance element. The control circuit causes the variable resistance element to change from a first resistance state to a second resistance state by having a first current flow from the first end to the second end of the variable resistance element. In addition, after a second current smaller than the first current is made to flow from the first end to the second end of the variable resistance element, the control circuit causes the variable resistance element to change from the second resistance state to the first resistance state by having a third current flow from the second end to the first end thereof.

  • Patent number: 9042156
    Abstract: A semiconductor memory device includes a writing circuit and a reading circuit. The writing circuit executes a setting action for converting a resistance of a variable resistance element to a low resistance by applying current from one end side to the other end side of a memory cell via the variable resistance element, and a resetting action for converting the resistance to a high resistance by applying current from the other end side to the one end side via the variable resistance element. The reading circuit executes a first reading action for reading a resistance state of the variable resistance element by applying current from one end side to the other end side of the memory cell via the variable resistance element, and a second reading action for reading the resistance state by applying current from the other end side to the one end side via the variable resistance element.

  • Patent number: 8980722
    Abstract: A variable resistive element comprising a configuration that an area of an electrically contributing region of a variable resistor body is finer than that constrained by an upper electrode or a lower electrode and its manufacturing method are provided. A bump electrode material is formed on a lower electrode arranged on a base substrate. The bump electrode material is contacted to a variable resistor body at a surface different from a contact surface to the lower electrode. The variable resistor body is contacted to an upper electrode at a surface different from a contact surface to the bump electrode material. Thus, a cross point region between the bump electrode material (the variable resistor body) and the upper electrode becomes an electrically contributing region of the variable resistor body, and then an area thereof can be reduced compared with that of the region regarding the conventional variable resistive element.

    Abstract: A method of a forming process for a variable resistive element, which is performed in short time comparable to the pulse forming and a writing current in a switching action is the same level as that of the DC forming, is provided. In the forming process, a variable resistive element is changed by voltage pulse application from an initial high resistance state just after produced to a variable resistance state where the switching action is performed. The forming process includes a first step of applying a first pulse having a voltage amplitude lower than a threshold voltage at which the resistance of the variable resistive element is lowered, to between both electrodes of the variable resistive element, and a second step of applying a second pulse having a voltage amplitude having the same polarity as the first pulse and not lower than the threshold voltage, thereto after the first step.
