Design of Ultra-low Power SRAMs for IoT, security and Computation-in-Memory
Tony Kim Tae Hyoung, Nanyang Technological University, Singapore

Abstract: Recently, various ultra-low power applications such as Internet-of-Things (IoT), wearable devices, biomedical devices, AI, and machine learning have emerged opening up a new domain of integrated circuits design. In these applications, ultra-low voltage circuit techniques for improving the power and energy efficiencies have been the main research focus. One of the most challenging functional blocks in ultra-low power systems is memory where SRAMs are dominantly employed. Since SRAMs occupy majority of the power in those systems, design of ultra-low power SRAMs is a critical task for power and energy efficiencies. In addition, SRAMs have started to be employed in realizing Physically Unclonable Function (PUF) and Computation-in-Memory (CIM). Even though basic SRAM design methodologies can be adopted in these applications, several additional design challenges need to be carefully addressed. This tutorial will present the basics in ultra-low power SRAMs followed by state-of-the-art ultra-low power SRAM design techniques. Design challenges and several methodologies for SRAM-based PUFs and SRAM-based CIM will also be explained. Finally, I will discuss future directions in ultra-low power SRAMs including various emerging non-volatile memory devices such as STTRAM, RRAM, etc.

Internet of Things (IoT): Signals, Communications, Applications, Challenges, and Future Research
Ahmed Abelgawad, Central Michigan University, USA

Abstract: Internet of Things (IoT) is the network of physical objects or “things” embedded with electronics, software, sensors, and network connectivity. It enables the objects to collect, share, and analyze data. The IoT has become an integral part of our daily lives through applications such as public safety, intelligent tracking in transportation, industrial wireless automation, personal health monitoring, and health care for the aged community. IoT is one of the latest technologies that will change our lifestyle in the coming years. Experts estimate that as of now, there are 23 billion connected devices, and by 2020 it would reach 30 billion devices. This tutorial aims to introduce the design and implementation of IoT systems. The foundations of IoT will be discussed throughout real applications. Challenges and constraints for future research in IoT will be discussed. In addition, research opportunities and collaboration will be offered for the attendees.

We will proceed to give an overview of the new and exciting field of using AI chips to accelerate deep learning computations. It will cover the critical and special characteristics and the architecture of the most popular AI chips. Next we will summarize the features of the AI chips from design-for-test (DFT) perspective and introduce the DFT technologies that can help testing AI chips and speeding up time-to-market.

Offset Mitigation in Low-Voltage Sense Amplifiers and Its Implication on SRAM Design and Test
Manoj Sachdev, University of Waterloo, Canada

Abstract: Static Random Access Memories (SRAMs) often occupy a significant area of contemporary Systems on Chip (SoC) integrated circuits (ICs) and therefore determine their energy consumption, yield, and reliability. The sense amplifier (SA) is a critical SRAM circuit that requires careful design. The offset in the SA does not scale well with technology scaling and has become an impediment to realizing energy efficient SRAMs. Additionally, the offset in SAs can also give rise to intermittent failures (soft-failures) in SRAMs that are difficult to detect through traditional march test algorithms.
This tutorial is divided into two parts. The first part focuses on SA design and contrasts techniques for mitigating SA offset voltage. The second part addresses SRAM design and test considerations for the SA offset voltage. Traditional approaches of SRAM testing are inadequate to cover SA offset related failures, and we highlight algorithmic and Design for Testability (DfT) techniques for detecting such failures. The tutorial draws data from several different publications, as well as from several test chips designed by the presenter and his graduate students.
