Short Description

For decades, conventional computers based on the von Neumann architecture have performed computation by repeatedly transferring data between their processing and their memory units, which are physically separated. As computation becomes increasingly data-centric and as the scalability limits in terms of performance and power are being reached, alternative computing paradigms are searched for in which computation and storage are collocated. A fascinating new approach is that of computational memory where the physics of nanoscale memory devices are used to perform certain computational tasks within the memory unit in a non-von Neumann manner.

Computational memory is finding applications in a variety of application areas such as machine learning and signal processing [1]. Most importantly, it is very appealing for making energy-efficient deep learning inference hardware, where the neural network layers would be encoded in crossbar arrays of memory devices [2]. However, there are several challenges that need to be overcome at both hardware and algorithmic levels to realize reliable and accurate inference engines based on computational memory.

We are inviting applications from students to conduct their Master thesis work or an internship project at IBM Research – Zurich on this exciting new topic. The work performed could span low-level hardware experiments on phase-change memory chips comprising more than 1 million devices to high-level algorithmic development in a deep learning framework such as TensorFlow or PyTorch. It also involves interactions with several researchers across IBM research focusing on various aspects of the project. The ideal candidate should have a multi-disciplinary background, strong mathematical aptitude and programming skills. Prior knowledge on emerging memory technologies such as phase-change memory is a bonus but not necessary.
