Transforming Nanodevices into Nanosystems: The N3XT 1,000X

Host: Prof. Onur Mutlu

ABSTRACT:

Coming generations of information technology will process unprecedented amounts of loosely-structured data, including streaming video and audio, natural languages, real-time sensor readings, contextual environments, or even brain signals. The computation demands of these abundant-data applications (e.g., deep learning) far exceed the capabilities of today’s computing systems, and cannot be met by isolated improvements in transistor technologies, memories, or integrated circuit (IC) architectures alone. Transformative nanosystems, which leverage the unique properties of emerging nanotechnologies to create new IC architectures, are required to deliver unprecedented functionality, performance and energy efficiency. However, emerging nanomaterials and nanodevices face major obstacles such as inherent imperfections and variations. Thus, realizing working circuits, let alone transformative nanosystems, has been infeasible. The N3XT (Nano-Engineered Computing Systems Technology) approach overcomes these challenges through recent innovations across the computing stack: (a) new logic devices using nanomaterials such as one-dimensional carbon nanotubes (and two-dimensional semiconductors) for high performance and energy efficiency; (b) high-density non-volatile resistive and magnetic memories; (c) ultra-dense (e.g., monolithic) three-dimensional integration of thin layers of logic and memory with fine-grained connectivity; (d) new IC architectures for computation immersed in memory; and, (e) new materials technologies and their integration for efficient heat removal. N3XT hardware prototypes represent leading examples of transforming the basic science of nanomaterials and nanodevices into actual nanosystems. Compared to conventional (2D) systems, N3XT architectures promise to improve the energy efficiency of abundant-data applications significantly, in the range of three orders of magnitude. Such massive benefits enable new frontiers of applications for a wide range of computing systems, from embedded systems to the cloud.

BIOGRAPHY:

Subhasish Mitra is Professor of Electrical Engineering and of Computer Science at Stanford University, where he directs the Stanford Robust Systems Group and co-leads the Computation focus area of the Stanford SystemX Alliance. He is also a faculty member of the Stanford Neurosciences Institute. Before joining the Stanford faculty, he was a Principal Engineer at Intel Corporation. Prof. Mitra's research interests range broadly across robust computing, nanosystems, VLSI design, CAD, validation and test, and neurosciences. He, jointly with his students and collaborators, demonstrated the first carbon nanotube computer and the first 3D Nanosystem with computation immersed in memory. These demonstrations received wide-spread recognitions (cover of NATURE, research highlight to the United States Congress by the National Science Foundation, highlight as "important, scientific breakthrough" by the BBC, Economist, EE Times, IEEE Spectrum, MIT Technology Review, National Public Radio, New York Times, Scientific American, Time, Wall Street Journal, Washington Post and numerous others worldwide). His earlier work on X-Compact test compression has been key to cost-effective manufacturing and high-quality testing of a vast majority of electronic systems. X-Compact and its derivatives have been implemented in widely-used commercial Electronic Design Automation tools. Prof. Mitra's honors include the ACM SIGDA/IEEE CEDA Richard Newton Technical Impact Award in Electronic Design Automation (a test of time honor), the Semiconductor Research Corporation's Technical Excellence Award, the Intel Achievement Award (Intel’s highest corporate honor), and the Presidential Early Career Award for Scientists and Engineers from the White House (the highest United States honor for early-career outstanding scientists and engineers). He and his students published several award-winning papers at major venues: IEEE/ACM Design Automation Conference, IEEE International Solid-State Circuits Conference, IEEE International Test Conference, IEEE Transactions on CAD, IEEE VLSI Test Symposium, and the Symposium on VLSI Technology. At Stanford, he has been honored several times by graduating seniors "for being important to them during their time at Stanford." Prof. Mitra served on the Defense Advanced Research Projects Agency's (DARPA) Information Science and Technology Board as an invited member. He is a Fellow of the ACM and the IEEE.
