In this work, a NAND memory architecture utilizing
enhanced Ferroelectric Field Effect Transistor (FEFET)
based on IGZO thin-film is presented. The enhanced
ferroelectric characteristics is achieved via interlayer (IL)
engineering using TiN/W. The optimized FEFET exhibits
large MW of 3.6 V, multiple states operation (3-bits) and
endurance exceeding 109 cycles. Consequently, a string of
NAND memory formed by 8 FEFETs was fabricated,
where an operating scheme suitable for FEFET-based
NAND array is proposed and experimentally
demonstrated. Our results will pave a potential pathway
for the use of FEFET in NAND architecture for future
high-density storage and computing applications.
