Opportunities and Challenges in Multi-Times-Programmable Floating-Gate Logic Non-Volatile Memories

Low bit count floating gate (FG) logic NVM (LNVM) developed in baseline logic process is finding increasing use in system-on-chip (SOC) ICs due to its low cost and absence of extra process integration needs. This paper reviews the opportunities this technology brings to the eNVM fields and the technical challenges it faces. It also demonstrates that FG logic NVM is scalable to have 50A tunneling oxide to store the charge at 65 nm CMOS technology node and beyond.
