Scalable and robust multi-bit spintronic synapses for analog in-memory computing

The pursuit of high-performance and energy-efficient computing for data-intensive algorithms such as deep neural networks (DNN) opens up exciting opportunities for emerging non-volatile memories (NVM). Particularly, implementing such non-volatile memory units in crossbar arrays as weight matrix storage can provide highly parallel and efficient means of processing matrix-vector multiplications, providing synaptic functionality for the neuromorphic computing paradigm. While numerous memristive and
