Abstract
Asymmetric Field Cycling Recovery (AFCR) with a low E-field is proposed for the first time to extend the endurance cycles of a ferroelectric (FE) capacitor and is experimentally demonstrated for 200 periods and accumulated to 10 12 switching cycles. Positive and negative Asymmetric minor loops (AmL) with AFCR achieve the nondegradation and complete restoration of $\triangle 2 \mathrm{P}_{\mathrm{r}}$ toward the prospect of unlimited operation. Furthermore, an FeRAM array circuit with an inverting amplifier is designed to execute the Write/Read and Recovery procedures simultaneously by AFCR scheme.
