High On/Off Ratio Spintronic Multi‐Level Memory Unit for Deep Neural Network (Adv. Sci. 13/2022)

Spintronic Multi‐Level Memory Unit In article number 2103357 by Kun Zhang, Yue Zhang, and co‐workers, a spintronic multi‐level memory unit (MLMU) with high on/off ratio is constructed by integrating a magnetic tunnel junction chain and a diode in parallel. This MLMU can enable high‐accuracy artificial intelligence applications, such as a deep neural network accelerator for image classification. Just as described in the cover design, the MLMUs are regarded as building blocks to assemble the artificial‐intelligence brain. [Image: see text]
