Title: „In-memory and Neuromorphic Computing“: Accelerating AI Applications

 

In today’s computing systems based on the conventional von Neumann architecture, there are distinct memory and processing units. Performing computations results in a significant amount of data being moved back and forth between the physically separated memory and processing units.

This costs time and energy and constitutes an inherent performance bottleneck. It is becoming increasingly clear that for AI application areas, we need to transition to computing architectures in which memory and logic coexist in some form. Brain-inspired neuromorphic computing and the fascinating new area of in-memory computing or computational memory are two key non-von Neumann approaches being researched. A critical requirement in these novel computing paradigms is a very-high-density, low-power, variable-state, programmable and non-volatile nanoscale memory device. There are many examples of such nanoscale memory devices in which the information is stored either as charge or as resistance. However, one particular example is phase-change-memory (PCM) devices, which are very well suited to address this need, owing to their multi-level storage capability and potential scalability.

 

In in-memory computing, the physics of the nanoscale memory devices, as well as the organization of such devices in crossbar arrays, are exploited to perform certain computational tasks within the memory unit.

We will present how computational memories accelerate AI applications and will show small- and large-scale experimental demonstrations that perform high-level computational primitives, such as ultra-low-power inference engines, optimization solvers including compressed sensing and sparse coding, linear solvers and temporal correlation detection.

Moreover, we will discuss the efficacy of this approach to efficiently address not only inferencing but also training of deep neural networks.

In neuromorphic computing, we explore power- and area-efficient hardware architectures for learning systems that are inspired by the structure and the functioning principles of the brain. We will present how the biologically-feasible spiking neurons and synapses can be implemented in an all-PCM architecture and will show experimental demonstrations of unsupervised and supervised learning. The results of in-memory and neuromorphic computing show that this co-existence of computation and storage at the nanometer scale could be the enabler for new, ultra-dense, low-power, and massively parallel computing systems. Thus, by augmenting conventional computing systems, in-memory and neuromorphic computing could help achieve orders of magnitude improvement in performance and efficiency.
