Self-compliance I-V switching characteristics and fitting. (a) Self-compliance Repeatable I-V hysteresis loop of our IrOx/GdOx/W cross-point memory devices. A low operation voltage of ±3 V is applied to get repeatable resistive switching characteristics. (b) Fitted I-V curve in a log-log scale. Both LRS and HRS show trap-controlled space charge-limited current conduction mechanism.
