Abstract
A resistance change memory device includes: a memory cell formed of a variable resistance element and a diode connected in series, the state of the variable resistance element being reversibly changed in accordance with applied voltage or current; and a stabilizing circuit so coupled in series to the current path of the memory cell as to serve for stabilizing the state change of the memory cell passively.
