Popis: We report 1-3 bit/cell FeFET operation through optimized HSO and HZO ferroelectric laminate layers using alumina interlayers. Memory window up to 3.5V, switching speed of 300ns, 10 years retention, and 104 endurance are reported. The gate stack lamination merits are discussed with insight potential of FeFET as an MLC memory.
