Fatigue Mechanism of Antiferroelectric Hf0.1Zr0.9O2 Toward Endurance Immunity by Opposite Polarity Cycling Recovery (OPCR) for eDRAM

Abstract: Opposite polarity cycling recovery (OPCR) isproposed to completely restore a fatigued antiferroelectric (AFE) capacitor back to its initial state, thereby extending the endurance number of switching cycles for AFE-RAM. A comprehensive model exclusive to AFE with unipolar cycling is revealed to achieve unlimited endurance, and the unipolar cycling with OPCR is experimentally demonstrated to accumulate 10 12 cycles, while achieving the nondegradation and complete restoration of the remnant polarization (P r ).
