Patent ID: 7995372

Claim:
A resistance change memory device comprising 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, wherein the stabilizing circuit includes: a first transistor so coupled in series to the memory cell as to prevent the memory cell from being applied with set-use voltage when the memory cell held in a set state with a low resistance state is applied with reset-use current to be changed to a reset state with a high resistance; and a second transistor so coupled in series to the first transistor as to prevent the memory cell from being applied with reset-use current when the memory cell held in the reset state is applied with set-use voltage to be changed to the set state.
