摘要： PROBLEM TO BE SOLVED: To provide a memory element capable of improving repetition durability, and to provide a memory device. SOLUTION: A resistance change layer 22 contains aluminum oxide (AlOx) and transition metal oxide having low resistance relative to that of the aluminum oxide. Specifically, the resistance change layer 22 has a structure where a first layer 22A formed of the transition metal oxide and a second layer 22B containing the aluminum oxide as a main constituent are laminated in an order from the side of a lower electrode 10. When a positive voltage is applied to this element, voltage bias is hardly applied to the first layer 22A. Thereby, even when the element comes into a write state (low-resistance state), the first layer 22A is not reduced and the oxide film is kept formed on the lower electrode 10. Accordingly, an unnecessary oxidation reaction between a chalcogen element included in an ion source layer 21 and the lower electrode 10 is prevented from occurring with repetition of write and erasure.

摘要翻译：要解决的问题：提供能够提高重复耐久性的存储元件，并提供存储器件。解决方案：电阻变化层22包含相对于氧化铝具有低电阻的氧化铝（AlO x）和过渡金属氧化物。具体而言，电阻变化层22具有从下部电极10的侧面依次层叠由过渡金属氧化物形成的第一层22A和含有氧化铝作为主要成分的第二层22B的结构。当对该元件施加正电压，几乎不向第一层22A施加电压偏置。因此，即使当元件进入写入状态（低电阻状态）时，第一层22A也不会减小，并且氧化膜保持形成在下部电极10上。因此，包含在第二层22A中的硫属元素之间的不必要的氧化反应防止重复写入和擦除而发生离子源层21和下部电极10。版权所有（C）2011，JPO＆INPIT
