Patent attributes
A resistance change memory device including: a substrate; cell arrays stacked thereabove, each including a matrix layout of memory cells; a write circuit configured to write a pair cell constituted by two neighboring memory cells; and a read circuit configured to read complementary resistance value states of the pair cell as one bit of data, wherein the memory cell includes a variable resistance element for storing as information a resistance value, which has a recording layer composed of a composite compound containing at least two types of cation elements, at least one type of the cation element being a transition element having “d”-orbit, in which electrons are incompletely filled, the shortest distance between adjacent cation elements being 0.32 nm or less.
