Approaching the Information Theoretical Bound of Multi-Level NAND Flash Memory Storage Efficiency
Shu Li, Tong Zhang · 2009
This paper applies information theory to formulate and estimate the NAND flash memory storage efficiency bound, and shows a big gap between the theoretical bound and what is achievable today. We further present two techniques to reduce the gap and demonstrate their promising potential using 2 bits/cell NAND flash memories as a test vehicle.
