Memory manufacturing, architectures, design and test were deeply investigated in-depth to address issues linked to technology scaling such as increasing static power, maximum operating frequency and the gap between logic and memory minimum voltages. Various emerging memories solutions have appeared in recent years with the aim to replace either partially or completely already existing memories in order to overcome both technology and design related limitations while giving answers to the aggressive requirements of many different applications. The goal of this Workshop is to bring together researchers, practitioners, designers and other people interested in this exciting and rapidly evolving field, in order to update each other on the latest state-of-the-art, exchange ideas, and discuss the future challenges and trends.

Subjects of interest

You are invited to participate and submit your contributions to DATE 2017 Friday Workshop on Emerging Memory Solutions. The areas of interest include (but are not limited to) the following topics:

  • Volatile memory design (SRAM, DRAM, CAM, etc.)
  • Non-Volatile memory design (ReRAM, Flash, PCM, MRAM, etc.)
  • Applications of emerging devices in memories (TFETs, CNTs, nanowires, etc.)
  • 3D memories (volatile and non-volatile)
  • In-Memory and Near-Memory Processing
  • Memory Application for emerging markets
  • Memory test, BIST and debug techniques
  • Applications, products and prototypes of new memories


The panel of the workshop will be about the topic "Can We Jump over the Memory Wall with In-Memory Computing?". We looking forward to a very lively discussion moderated by our panel chair Ian O'Connor.

In the future new memory systems and technologies will appear, but what are the implications on the programming models in a few years from now.

Prof. Bruce Jacob:

Bruce Jacob is a Keystone Professor of Electrical and Computer Engineering and former Director of Computer Engineering at the University of Maryland in College Park. He received the AB degree in mathematics from Harvard University in 1988 and the MS and PhD degrees in CSE from the University of Michigan in Ann Arbor in 1995 and 1997, respectively. He holds several patents in the design of circuits for electric guitars and started a company around them. He also worked for two successful startup companies in the Boston area: Boston Technology and Priority Call Management. At Priority Call Management he was the initial system architect and chief engineer. He is a recipient of a US National Science Foundation CAREER award for his work on DRAM, and he is the lead author of an absurdly large book on the topic of memory systems. His research interests include system architectures, memory systems, operating systems, and electric guitars.

10:30W02.4.1Cortical Processors and Memories!
Paul Franzon, NC State University, US


There has been strong recent interest in machine learning algorithms that are capable of unsupervised learning and incremental learning. A subset of these algorithms are cortically inspired, that is inspired by presumptive models of how the brain works at higher levels, i.e. at the cortical levels. Examples of such algorithms include Sparsey, Hierarchical Temporal Memory, LSTM and Cogent Confabulation.  We have been designing and building accelerators for these algorithms. We will review these algorithms in some detail. Two versions were designed - a programmable 65 nm SIMD version with Processor in Memory (PiM) extensions and a 65 nm ASIC version. They were compared against a 28 nm GPU baseline using the KTH video action recognition benchmark. Performance/power improvement over the GPU were (Sparsey) SIMD with PiM: 1490; ASIC: 1300; and (HTM) SIMD with PiM: 537; ASIC: 47,100.  Part of the SIMD design is being fabricated as a 3DIC.  Memory bandwidth and capacity is a key bottleneck in many of these algorithms.  Codesigned 3D solutions provide specific advantages.

In current conventional computing systems the data is usual transported with a tremendous effort and energy to the computing cores. This has a lot of drawbacks. Thus, near-memory or in-memory computing has evolved as new emerging trend. We will have a spotlight on the advantages and disadvantages of this novel research area.

13:00W02.6.1Keynote: Energy-Efficient Processing and Why the Memory Matters
Borivoje Nikolic, UC Berkeley, US

Abstract: New computing applications demand increased system capability, but the end of Moore's Law scaling also means the end of traditional approaches based on scaling conventional general-purpose computing architectures. New architectures and accompanying circuit implementations are required to develop efficient specialized chips for different markets. To provide for ultimate energy efficiency in a broad scope of applications ranging from future mobile clients to warehouse-scale computers (WSCs), the new architectures will optimally utilize a computing substrate based on ultimately scaled CMOS and some of the key emerging device, interconnect and memory technologies. While workloads are constantly changing, the underlying computational primitives are not. The 13 Berkeley computational motifs as the key computational kernels across a wide range of current and emerging applications. By optimally implementing specialized engines for these motifs, including both computation and data movement, optimal energy efficiency can be achieved over a broad range of application domains and underlying technologies.  This talk presents approaches to implementing specialized computing platforms and presents the role of traditional and emerging memory technologies in them.
