Abstract :
1T1R-architecture devices were fabricated by integrating ZrO2 based crossbar structure ReRAM onto a foundry-built MOSFET platform. Multilevel operation was realized by using the current limit of a selected cell transistor in the set process. The current level was determined by the transistor´s gate voltage, resulting in the control of electrical resistance of the filamentary conductive paths in the low resistive state.
