Patent number: 7978047Abstract: A variable resistance element comprises a variable resistor of strongly-correlated material sandwiched between two metal electrodes, and the electric resistance between the metal electrodes varies when a voltage pulse is applied between the metal electrodes. Such a switching operation as the ratio of electric resistance between low and high resistance states is high can be attained by designing the metal electrodes and variable resistor appropriately based on a definite switching operation principle. Material and composition of the first electrode and variable resistor are set such that metal insulator transition takes place on the interface of the first electrode in any one of two metal electrodes and the variable resistor by applying a voltage pulse. Two-phase coexisting phase of metal and insulator phases can be formed in the vicinity of the interface between the variable resistor and first electrode by the work function difference between the first electrode and variable resistor.Type: GrantFiled: August 8, 2006Date of Patent: July 12, 2011Assignees: Sharp Kabushiki Kaisha, National Science and TechnologyInventors: Yasunari Hosoi, Shigeo Ohnishi, Yasushi Ogimoto, Takashi Oka, Naoto Nagaosa, Yoshinori Tokura
