    摘要: According to one embodiment, an information recording/reproducing device includes a recording layer and a driver section. The recording layer has a first layer including a first compound. The first compound includes a mixed crystal of a first oxide containing a first metallic element and a second oxide. The second oxide has a crystal structure being same as the first oxide and contains a second metallic element different from the first metallic element. The driver section is configured to produce state change in the recording layer to record information by at least one of application of voltage to the recording layer and passage of current to the recording layer. Composition ratio of an element having a smaller ionic radius of the first and second metallic elements is not less than percolation threshold of a lattice formed of ions of the first and second metallic elements based on the crystal structure.

    摘要: According to one embodiment, a non-volatile memory device includes a stacked structure and a voltage application portion. The stacked structure includes a memory portion, and an electrode stacked with the memory portion and having a surface having a portion facing the memory portion. The voltage application portion applies a voltage to the memory portion to cause a change in a resistance in the memory portion to store information. The surface includes a first region and a second region. The first region contains at least one of a metallic element, Si, Ga, and As. The first region is conductive. The second region contains at least one of the metallic element, Si, Ga, and As, and has a content ratio of nonmetallic element higher than a content ratio of nonmetallic element in the first region. At least one of the first region and the second region has an anisotropic shape on the surface.

    摘要: According to one embodiment, a non-volatile memory device includes a stacked structure including a memory portion and an electrode having a surface facing the memory portion; and a voltage application portion to apply a voltage to the memory portion to change resistance. The surface includes first and second regions. The first region contains a first nonmetallic element and at least one element of a metallic element, Si, Ga, and As. The second region contains a second nonmetallic element and the at least one element. The second region has a content ratio of the second nonmetallic element higher than that in the first region. A difference in electronegativity between the second nonmetallic element and the at least one element is greater than that between the first nonmetallic element and the at least one element. At least one of the first and second regions has an anisotropic shape.
