Spin-Valve Interface for Magnetic Quantum Dot Cellular Automata

CMOS technology is reaching its physical limits in terms of scaling, and this is leading many researchers to investigate alternative computing technologies. As the industry moves away from CMOS and toward other technologies, it will be necessary to explore new ways of transporting data. This thesis explores a novel application of two relatively new technologies, magnetic quantum dot cellular automata and spin-valve technology, with a focus on existing work in magnetic random access memory. To move forward in the real-life implementation of new computing technologies, some new engineering will be necessary to bridge the gap between extant CMOS computing technology and this new area of magnetic logic and storage. With a view toward promoting this, the spin-valve-based Magnetic- Electric Interface (MEI) was developed. Topics covered in this thesis include the state of the art of the technology behind MQCA as well as the reasons for using it, spin-valve technology such as MRAM, the reasons for development of, rationale for and design behind the MEI, and potential applications of the technology for development of MQCA computing systems.
