| 简介 |
A nonvolatile memory element in which Rb1-yMbyMnO3 having higher insulation properties than Ra1-xMaxMnO3 is inserted between the Ra1-xMaxMnO3 and a metal having a shallow work function or a low electronegativity in order to improve resistance change properties and switching properties and to control the resistance change properties. (In the formulas, Ra and Rb represent rare earth elements and are solid solutions of one or more types of rare earth elements. Average ionic radius of the Rb is smaller than that of the Ra. Ma and Mb represent alkaline earth metals and are solid solutions of one or more types of alkaline earth metals. 0
