The ferroelectric (FE) NAND flash, featuring metal-interlayer-FE-interlayer-silicon (MIFIS) gate stacks, leverages both charge trapping and polarization (P) switching to achieve a broad memory window (MW) and low operation voltage. These remarkable advancements establish it as a viable contender for future NAND flash technologies. However, the read-after-write-delay (RAWD) problem during program/e...Show More
In this study, we investigated the impact of unstable and stable interface trap charges ( ${Q}_{\text {it}}\text {)}$ on ${P}_{\text {S}}$ switching in metal-ferroelectric–insulator-Si (MFIS) ferroelectric field-effect transistors (FeFETs), which vary with the thickness of the insulator. We also examine how these variations ultimately affect the various performance metrics of MFIS FeFETs. To ac...Show More
