Spin-electronics based logic fabrics

Advanced computing ICs in ultra deep-micron technology nodes (e.g. 40 nm) suffer from high power issues, which become one of the major bottlenecks for the future performance progress. Both static and dynamic power dissipation are increasing, caused mainly by the intrinsic leakage currents and large data traffic. Alternative approaches beyond charge-based logic circuits become hot research topics to overcome these issues definitively. By integrating the spin freedom of electrons to electronic devices, spin-electronics is promising for ultra-low power computing as it can provide non-volatility, fast data control and high logic density etc. Today, most of large microelectronics industries investigate this emerging field. In this invited paper for the special session “Nanoscale logic fabrics”, we overview spin-electronics based logic fabrics under intense investigation and address particularly the impact of this technology on logic architectures and new computing paradigms.
