Enable disruptive computing for AI with novel memory technology
Imec is a world-leading research and innovation hub in nanoelectronics and digital technologies. The machine learning program at Imec is leading the quest for computationally- and energy-efficient machine learning accelerators. By leveraging its memory technology, Imec aims to develop analog in memory computing (AiMC) solutions built on emerging non-volatile memory devices. These devices can mitigate the challenges related to learning algorithms, by performing the computations in the memory itself. Compared to classical Von Neumann architectures, in which computations are performed on a central processor after memory elements have been fetched from outside, compute-in-memory approaches have the promise to increase energy efficiency by orders of magnitudes, while at the same time allowing for the required high throughput. Imec‘s machine learning research is driving the co-evolution of hardware and algorithms needed to facilitate the move to this new computational paradigm
Analog In Memory Computing has established itself as an energy efficient candidate for a wide range of Deep Learning Inference hardware. Current research shows the limitations of devices to be used for neural network inference and training due to several non-idealities. This PhD topic will focus on algorithms to enable analog computing based on novel memory technology for deep learning. The approach adopted for such a system would require co-optimization at every abstraction level of a computing system, starting from algorithm, architecture, circuits to device engineering.
Imec has a research program on developing new algorithms, systems and devices for deep learning. The PhD topic will enable the long-term vision of this research program to define and engineer algorithms and memory devices apt for Deep Learning. The student will be supported and supervised by a group of researchers working on enabling disruptive technology solution in the AI domain.
This PhD will build on imec's experience of combining system level constraints for technology or semiconductor innovation. The student will focus on the STCO techniques to identify, explore and solve the bottlenecks of engineering algorithms and devices for Analog-In-Memory-Compute systems. The research will involve fundamental breakthrough in algorithm level techniques coupled with novel circuit and device technology to find an energy efficient solution for running deep learning algorithms. This topic would be classic example of System-Technology-Co-Optimization philosophy pursued in imec.
