Nonvolatile Flash Memory: An Overview

Event Date: April 23, 2008
Speaker: Souvik Mahapatra
Speaker Affiliation: ITT Bombay, India
Sponsor: Network for Computational Nanotechnology
Time: 2:30 PM
Location: EE 317
Open To: Acceptable for ECE694A

In this talk, we will review the memory program and erase operation of floating gate flash cells under both NAND and NOR architecture. The reliability issues, such as cycling endurance, retention and array disturbs will be reviewed next. Finally, the floating gate cell scaling challenges will be discussed, and flash memories having newer charge storage node (nitride, metal nanocrystals) will be reviewed.
