Title: “Analog In-Memory Computing for Deep Learning Inference“
Talking Points:
- What is analog in-memory computing (AIMC)?
- How mature is AIMC?
- What are the key open research topics and what’s next for AIMC?
Abstract
I will introduce analog in-memory computing based on non-volatile memory technology with a focus on the key concepts and the associated terminology. Subsequently, a multi-tile mixed-signal AIMC chip for deep learning inference will be presented. This chip fabricated in 14nm CMOS technology comprises 64 AIMC cores/tiles based on phase-change memory technology. It will serve as the basis to delve deeper into the device, circuits, architectural and algorithmic aspects of AIMC. Of particular focus will be achieving floating point-equivalent classification accuracy while performing the bulk of computations in the analog domain with relatively less precision. I will also present an architectural vision for a next generation AIMC chip for DNN inference. I will conclude with an outlook for the future.
