Title: Flash Memory Management for Embedded Systems 
Presenter: Dr. Zili Shao
Time: 3:00 PM , Thursday , 17 Jan 2013 
Location: Room 230, CS Building


Flash memory is driving a storage revolution with its pervasion in our daily lives. It can be found everywhere from consumer electronics such as cell phones, cameras, USB flash drivers, TVs and toys to enterprise storage systems such as SSDs and enterprise flash drivers. In this talk, I will introduce our recent work in flash memory management for embedded systems. In particular, two techniques: Real-time-FTL(Real-time NAND Flash Translation Layer) and DAC(Demand-based block level Address mapping scheme with two-level Caching mechanism), will be presented. In Real-Time-FTL, we present a flash translation layer that can greatly improve both the worst-case and average response time. In DAC, we propose a novel demand-based block-level address mapping scheme with two-level caching machanism for large-scale NAND flash storage systems, so the RAM footprint can be greatly reduced without sacrificing too much system response time.


Zili Shao received the Ph.D degree from the Department of Computer Science, University of Texas at Dalas, in 2005. Currently, he is an associat professor at the Department of Computing in the Hong Kong Polytechnic University。 His Research interests include embedded software and systems, real-time systems, and related industrial applications. He is an associate Editor(Subject Area: Memory Systems) for Journal of Systems Architecture: Embedded Software Design, and serves/served the technical program committees of many top conferences in the real-time embedded systems field(such as RTSS, ICCAD, DATE, CODES+ISSS, EMSOFT, ISLPED, ASP-DAC and LCTES).
