Speaker: Professor Tong Zhang
Faculty host: Professor Helen Li
As the computing industry is entering the multi-/many-core era and world-wide blossoming data centers are enabling a new data-intensive computing paradigm, the well-known memory-wall problem will inevitably become a much more critical issue in future computing systems. Tackling this grand challenge can potentially benefit from two technology trends: (i) Three-dimensional (3D) integration is becoming a technically and economically viable technology that can vertically stack and interconnect several active device planes with massive interconnect bandwidth; (ii) NAND flash memory has become an economically viable technology to penetrate into computing system memory hierarchy, and meanwhile several emerging memory technologies such as phase-change memory and spin-torque transfer memory show great promises to usher significant impact on computing system memory hierarchy. How to most effectively leverage these technology trends still faces a variety of challenges, which provides many exciting opportunities to pursue innovative research. At Rensselaer, we have been actively working in this broad research area, and in this talk I will review our recent and on-going research activities, including (1) development of 3D memory architecture and investigation of 3D processor-memory integration, (2) application of advanced signal processing and coding techniques to improve NAND flash memory system performance, and (3) development of circuit and system design techniques for emerging memory technologies.
