Interfacing Between Transpinnor Logic and Semiconductor Logic

"A new technology is now emerging, where the central role for electronics is not the electron charge - as in semiconductor technology - but its spin. The proposer is developing all-metal (no semiconductors) electronics, in which all functional elements arebased on giant magnetoresistance (GMR). The foundation for such all-metal devices is the transpinnorr, an active device that has shown amplification and logic capabilities. Nonetheless, semiconductor technology is deeply entrenched, and there will be aneed, for some time to come, to address the important issue of interfacing between transpinnor logic and semiconductor logic. This proposal addresses that opportunity. The proposed project will develop interfacing between these two logic technologies.Specific circuits for interfacing between transpinnor logic and semiconductor logic will be designed. The designs will be reviewed and evaluated by modeling and simulation. The Phase I project will provide the foundation for the fabrication in Phase II ofthe interfaces using the proposer's GMR technology. These interfaces will provide the necessary bridge to existing semiconductor products. All-metal technology has applications in nearly the entire electronics and storage markets presently held by thesemiconductor and hard-drive technologies. For most of these, it will have significant performance and cost advantages over both semiconductor devices and hybrid magnetic/semiconductor devices.
