In this paper, a circuit model of the filamentary-type resistive memory cell was proposed for RRAM array circuit simulations. DC characteristics are fitted for fabricated and measured RRAM devices by optimizing three resistor elements. Transient characteristics of the model have been investigated. It was found that switching characteristics can be improved by minimizing the parasitic capacitances. For different materials and conduction mechanisms, the characteristics of resistive memories can be fitted simply by controlling several parameters.
