Maximizing Mutual Information in Flash Memories

Explore the challenges and optimization techniques for Flash memory communication in this 41-minute lecture by Richard Wesel from UCLA. Delve into the unique characteristics of Flash memory cells, which store multiple bits but face constraints similar to multiple access channels. Examine how the Flash controller's read operation, akin to a one-bit analog-to-digital converter, impacts information extraction. Learn about the application of mutual information maximization in designing Flash write levels and read thresholds. Discover how this approach can lead to optimal performance of LDPC codes and extend the lifespan of Flash devices. Gain insights into application-driven coding theory and its practical implications for improving Flash memory reliability and efficiency.
