大会特邀报告4：Opportunities and Challenges Faced by DRAM/Flash/NVRAM Technologies

报告摘要:

Big data applications demand high speed, reliable, and energy efficient data storage systems. Traditional storage architectures have fundamental limitations because of legacy systems that have centered on spinning hard disk drives. With rapid advances in DRAM and nonvolatile memories such as NAND-gate flash, phase change memory, Memristor, and magnetic RAM, a great opportunity exists for optimizing storage architectures. This talk will summarize recent developments in semiconductor memory technologies and their potential roles in storage systems. From system architecture perspective, we analyze respective significance of each memory technology. To build optimal storage systems, storage hierarchy is the way to go. We introduce a new concept: 'Content Locality' for storage hierarchy design. Based on this new concept, various memory/storage architectures will be presented and compared in terms of how they exploit the physical properties of various memory technologies as well as memory access behaviors at customer sites. Quantitative evaluations of memory performances and market trend will be discussed and explored as well.
