The objective of this research is to demonstrate the feasibility of using spintronics-based magnetic tunnel junction devices to implement complex digital systems. The approach is to design and fabricate a single-bit full adder at the NSF-supported University of Minnesota Nanofabrication Center using the prototype magnetic tunnel junction devices previously demonstrated by the investigators. Concurrently with this fabrication process, a multi-operation bit-serial function unit that will take advantage of the programmability of the magnetic gates will be designed and simulated. The ultimate goal beyond this initial feasibility study is to design a fully functional processor entirely from these novel non-charge-based spintronics devices.The primary intellectual merit of this project is the development of new techniques and circuits that will lead to an understanding of how to construct complex computational elements from the magnetic tunnel junction gates. The innovative exploitation of this emerging technology will significantly expand the understanding of spintronics devices to eventually incorporate the potential advantages of this technology into future systems. Due to the highly exploratory nature of this work, it is unlikely that it would be pursued by industry. Yet it holds tremendous promise to help drive future computing trends, making it very appropriate for government support.Broader impacts of this project include multidisciplinary training of a new generation of researchers that emphasizes both device fabrication and computing, and opportunities for underrepresented groups to participate in an exciting new research area. Existing collaborations will help to quickly transfer to industry the novel technology developed in this project.

这项研究的目的是证明使用基于Spintronics的磁性隧道接线设备实现复杂的数字系统的可行性。这种方法是使用研究人员先前证明的原型磁性隧道接线设备在NSF支持的明尼苏达州纳米制造中心设计和制造单位完整的加法器。同时，将设计和模拟此制造过程，这是一个将利用磁门的可编程性的多操作位函数单元。除了这项最初的可行性研究之外，最终的目标是完全从这些基于非电荷的Spintronics设备设计完整的功能性处理器。该项目的主要智力优点是开发新技术和电路，这将导致如何理解如何从磁性隧道连接门中构建复杂的计算元素。对这项新兴技术的创新剥削将大大扩展对Spintronics设备的理解，最终将该技术的潜在优势纳入未来的系统。由于这项工作的高度探索性，行业不太可能追求它。然而，它具有巨大的希望，可以帮助推动未来的计算趋势，使其非常适合政府的支持。该项目的影响力的影响包括对新一代研究人员的多学科培训，这些研究人员强调了设备制造和计算，以及代表性不足的团体参加令人兴奋的新研究领域的机会。现有的合作将有助于快速转移到该项目中开发的新技术。
