Abstract
In this study, we experimentally demonstrated a simplified write inhibition bias scheme for a ferroelectric field-effect transistor (FeFET) based AND array, which is the promising energy- and area-efficient memory. The write inhibition scheme that only employs the bit line (BL) voltages was optimized through the single cell FeFET measurements. The program and erase operations were confirmed to be apparently inhibited with the BL/source line (SL) voltages of 3.5 V/0 V, respectively. The suggested inhibition bias scheme was then applied to the 16 × 16 FeFET AND array for demonstrating its validity. It was clearly verified that selective program/erase operations were possible without modulating the SL voltages, suggesting its benefits in terms of area-efficiency.
在本研究中，我们通过实验为基于铁电场效应晶体管（FeFET）的 AND 阵列演示了一种简化的写入抑制偏置方案，这是一种很有前途的节能、省面积存储器。通过对单芯片铁电场效应晶体管的测量，优化了只采用位线（BL）电压的写入抑制方案。经证实，位线/源线（SL）电压分别为 3.5 V/0 V 时，写入和擦除操作明显受到抑制。建议的抑制偏置方案随后被应用于 16 × 16 FeFET AND 阵列，以证明其有效性。结果清楚地证明，在不调节 SL 电压的情况下，可以进行选择性编程/擦除操作，这表明该方案在面积效率方面具有优势。
