The broader impact/commercial potential of this Partnerships for Innovation - Research Partnerships (PFI-RP) project is in providing a new hardware platform for energy-efficient and high-performance computing systems. The rise of big data has enabled the emergence of artificial intelligence (AI) in the cloud and on edge devices, and is fundamentally transforming the computing, networking and data storage industries. However, existing hardware cannot sustain the rapid growth of data-centric computing. In particular, fast and energy-efficient AI requires better embedded memory technologies (i.e. data storage devices inside computer chips) that are simultaneously fast to read and write, while delivering high capacities with low cost, along with low power consumption. This project will address this challenge by developing a novel type of on-chip magnetic memory device, focusing on its commercialization in the data storage, AI, communications and networking markets. The proposed project will develop a new type of magnetic random access memory (MRAM), referred to as voltage-controlled spin-orbit (VCSO) memory. MRAM is the leading contender for emerging AI systems due to its low power consumption and high endurance, and is entering volume manufacturing across the semiconductor industry after more than a decade of research and development. However, its current version suffers from density and speed limitations that limit its ultimate addressable market. This project will develop devices and memory arrays based on new physical principles and materials, which will allow the devices to overcome the physical limitations of existing MRAM, and achieve higher speeds with better scalability to smaller bit dimensions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这一创新-研究伙伴关系(PFI-RP)项目更广泛的影响/商业潜力在于为节能和高性能计算系统提供了一个新的硬件平台。大数据的兴起使人工智能(AI)在云和边缘设备上的出现成为可能，并正在从根本上改变计算、网络和数据存储行业。然而，现有的硬件无法支持以数据为中心的计算的快速增长。特别是，快速和节能的人工智能需要更好的嵌入式存储技术(即计算机芯片中的数据存储设备)，同时快速读取和写入，同时提供高容量和低成本，以及低功耗。该项目将通过开发一种新型的片上磁存储设备来应对这一挑战，重点是将其在数据存储、人工智能、通信和网络市场进行商业化。拟议的项目将开发一种新型的磁随机存取存储器(MRAM)，称为压控自旋轨道(VCSO)存储器。由于低功耗和高耐用性，MRAM是新兴人工智能系统的领先竞争者，经过十多年的研发，MRAM正在进入整个半导体行业的量产。然而，它目前的版本受到密度和速度的限制，限制了其最终的潜在市场。该项目将基于新的物理原理和材料开发设备和存储器阵列，这将允许设备克服现有MRAM的物理限制，实现更高的速度，并更好地扩展到更小的比特维度。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
