ABSTRACT:
A bipolar variable resistance device suitable for integrated circuit applications includes a silicon substrate, and a resistive layer covering the silicon substrate, the resistive layer being doped with impurities of a first polarity and of a second polarity. A dielectric layer covers the resistive layer. A conductive layer covers the dielectric layer. The device is used to change the resistance of the resistive layer by varying a control voltage applied to the conductive layer.
