The effect of operation current on the high-resistance state and the endurance for the \HfOX-based resistive device is comprehensively studied. Due to the current overshoot by the parasitic capacitances, an excess current leakage for the high-resistance state of the 1R device after the forming and SET stages is observed. The accelerated degradation of the high-resistance state for the \HfOX device undergoing a high-operation-current stage is revealed for the first time. As the compliance current increases beyond 500 \mu\A, the resistance of the high-resistance state of the device deceases drastically. A possible scenario about the correlation between the high-resistance state and the compliance current based on the filament model is proposed. By suppressing the current overshoot with the 1T1R device, the high-resistance state (> \1\ \M\Omega) and excellent endurance (> \10^8\ \cycles) for the \HfOX resistive memory are demonstrated.
