Foreword
A major issue today for the development of the Information and Communication Technologies is the challenge of the “beyond CMOS,” how to go beyond the physical limits of the semiconductor-based conventional electronics, how to continue the progress of the electronic components in terms of size, speed, and price reduction, with the additional challenge of treating and storing efficiently a continually increasing quantity of information while reducing the total energy consumption. If we look at the 2013 International Technology Roadmap for Semiconductors (ITRS), we can see that a major perspective for the “beyond CMOS” comes from spintronic technologies exploiting not only the charge of the electrons but also their magnetism, their spin. The book “Spintronics Based Computing” edited by Prof. Weisheng Zhao and Dr. Guillaume Prenat is particularly timely as it describes some of these spintronic technologies: Spin Transfer Torque-Random Access Memory (STT-RAM) and several types of logic or communication devices based on Magnetic Tunnel Junctions, STT-RAM, or Spin Torque Nano-Oscillators. The STT-RAM nonvolatile memories, owing mainly to their potential for the highly desirable reduction the energy consumption of computing, are included in v
