In this Review, we describe the working principles of STT-MRAM, and provide a brief history of its development. We then discuss the requirements, product status and outlook for four key STT-MRAM applications: stand-alone, embedded non-volatile memory, non-volatile working memory and last-level cache. Finally, we review potential future directions beyond STT-MRAM, including spin–orbit torque MRAM (SOT-MRAM) and voltage control of magnetic anisotropy MRAM (VCMA-MRAM), with an emphasis on their technological potential.

Complementary metal–oxide–semiconductor-based computing machines use orders-of-magnitude more computational resources than the brain on cognitive tasks that humans efficiently perform every day. As a result, we are witnessing a seismic shift in the field of computation. Research efforts are being directed to develop artificial intelligence (AI) hardware that mimics the human brain from a bottom-up perspective — through devices that are more naturally suited to neural computation — and thereby improves the efficiency of performing cognitive tasks. In the attempt to bridge the gap between neuroscience and electronics, here we report on developments in the field of spintronic devices for AI hardware. The dynamics of spintronic devices that can be used for the realization of neural and synaptic functionalities are discussed. A cross-layer perspective extending from the device to the circuit and system levels as a pathway towards efficient neural computing systems is also presented. Spintronic devices for artificial intelligence hardware can bridge the gap between neuroscience and electronics. Here we discuss the dynamics of such devices, enabling neural and synaptic functionalities, alongside a cross-layer approach — from devices to circuits and systems — for efficient neural computing systems.","PeriodicalId":501701,"journal":{"name":"Nature Reviews Electrical Engineering","volume":"1 11","pages":"714-729"},"PeriodicalIF":0.0,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142600833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Extrapolating these trends to the long term suggests that a switch, which is more energy-efficient than a silicon complementary metal-oxide semiconductor (CMOS) switch, is necessary to support future computing needs. Spintronic logic, which encodes information using spin and magnetism, can theoretically provide an energy-efficient switch; however, it is less mature than CMOS logic and has yet to be realized at the level of a full processor system, thus warranting an informed review of spintronic logic technologies with guidelines for future research directions. In this Review, we contextualize spintronic logic within the broader goals of beyond-CMOS computing. We then provide an overview of five types of spintronic logic, discussing the operating principles, advantages, advancements and challenges of each type. We highlight that future research in spintronic logic should focus on the realization of low-voltage operation, transparent benchmarking for application-level tasks, development of computing architectures that exploit unique features of spintronics such as non-volatility and high endurance, and adaptation of spintronic logic to circuits usable for both computing and memory. This Review provides motivation and direction for high-risk, high-reward research in spintronic logic that should be pursued in parallel with the CMOS road map. This Review showcases the research progress and prospects of spintronic logic, which encodes information using spin and magnetism. Focusing on five exemplary types, we discuss the promise, challenges and future research directions in the context of high-performance computing needs.","PeriodicalId":501701,"journal":{"name":"Nature Reviews Electrical Engineering","volume":"1 11","pages":"700-713"},"PeriodicalIF":0.0,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142600834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Automated recognition replicates the human process and analyses a face image, which is typically acquired with a visible spectrum sensor. When dealing with automated operational systems, the quality of the captured face image is relevant as it affects the recognition accuracy. Thus, it is necessary to measure the utility of a face sample with both a quality score and complementary measures that can provide actionable feedback. This Perspective addresses challenges and discusses solutions for the optimization of biometric recognition systems specifically related to face image analysis. One of these challenges is the vulnerability to presentation attacks. Consequently, for reliable recognition in non-supervised environments, robust presentation attack detection is required. Moreover, biometric templates must be protected. Finally, acceptability of biometric systems requires fairness of the biometric algorithms and artificial neural networks used. Automated face recognition systems are widely adopted in different operational systems, ranging from authentication with smart personal devices to access control and forensics. This Perspective analyses the critical challenges and proposed solutions for the optimized use of these recognition systems.","PeriodicalId":501701,"journal":{"name":"Nature Reviews Electrical Engineering","volume":"1 11","pages":"748-757"},"PeriodicalIF":0.0,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142600846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
