Abstract

The memory is the one of the main components of computer system as well as the key component for hand phone and cloud computing. For the last century, scaling has been being the main driving force for all of the current memory technologies in order to increase the density and reduce the cost. There are several kinds of memory to form a data storage hierarchy, such as DRAM,SRAM, Flash, optical disks, and hard disk drive. Although people have put a lot of effort to break scaling limitation, it could be estimated that all of above technologies might reach their scaling limits in about 10 to 15 years. On the other hand CPU also faces the same problem. Thus it is the time to find a new way to develop memory and CPU and to further develop computer. Brain like computer is one of the best approaches to solve the above problem. In this talk, the current statuses of memory and brain-like computer are briefly introduced. The requirement for the new memory technology to support brain-like computer is analyzed. The new memory should be capable of emulating some of brain functions. It should have the unique integrated function of storage and processing. The main problem and the possible approaches will be discussed.

Short Bio

Prof.Luping Shi received his Doctor of Science  from University of Cologne, Germany in 1992. In 1993, he worked as a Post-doctoral fellow in Fraunhofer Institute of Applied Optics and Precision Instrument, Jena, Germany. From 1994 to 1996, he worked as a research fellow in Department of Electronic Engineering, City University of Hong Kong. From 1996 to 2013 he worked in data storage institute, Singapore as a senior scientist and division manager and led nonvolatile solid-state memory (NVM) and artificial cognitive memory (ACM) and optical storage researches. He joined Tsinghua university, China, as a national distinguish professor and director of optical memory national engineering research center in Mar 2013. His main research areas include NVM, ACM, optical data storage, integrated opto-electronics, and nanoscience.  He has published more than 150 papers in prestigious journals including Science,  Nature Photonics, Advanced Materials, Physical Review Letters,  filed and granted more than 10 patents and conducted more than 60 keynote speech or invited talks at many important conferences during last 10 years. He is the recipient of the National Technology Award 2004 Singapore. He served as general co-chair of The 9th Asia-Pacific Conference on Near-field Optics2013, IEEE NVMTS 2011- 2014,East-West Summit on Nanophotonics and Metal Materials 2009 and ODS’2009.
