    摘要: An RRAM includes a resistive layer including a dielectric layer and surplus oxygen ions or nitrogen ions from a treatment on the dielectric layer after the dielectric layer is formed. When the RRAM is applied with a voltage, the oxygen ions or nitrogen ions occupy vacancies in the dielectric layer to increase resistance of the resistive layer. When the RRAM is applied with another voltage, the oxygen ions or nitrogen ions are removed from the vacancies to lower the resistance of the resistive layer.

    摘要: A non-volatile memory cell and the fabrication method thereof are provided. The non-volatile memory cell comprises a top electrode, a bottom electrode and an oxide layer disposed between the top electrode and the bottom electrode. The oxide layer comprises a relatively low oxygen content layer adjacent to the bottom electrode, a relatively high oxygen content layer adjacent to the top electrode, and a transition layer disposed between the relatively high and the relatively low oxygen content layers. The transition layer has an oxygen concentration within a range between those of the relatively high and the relatively low oxygen content layers.
