Zero standby power spintronics-based VLSIs
We have developed test chips of zero standby power spintronics-based VLSIs, such as
1) a high-speed, high-density, SRAM compatible non-volatile memory,
2) a high-speed fully-parallel data search engine, and
3) a three-dimensional stacked spin processor, which were fabricated on a 300mm wafer. We are making progress toward full demonstration of high density and high performance VLSIs that realize zero standby power electronics system for the energy saving society.

Recipient of IEEE David Sarnoff Award 2012
Professor Hideo Ohno received the IEEE David Sarnoff Award 2012 on 9 May 2012, in recognition of his leadership and contribution in the electronics division of the Institute of Electrical and Electronic Engineers (IEEE), the world’s largest academic society in the field of electricity and electronics, through his research combining semiconductor electronics and magnetic spintronics.

Revolutionary Change in Integrated Circuit Technology, the Foundation of Our Society
The program concurrently promotes the research and development of spintronics materials, devices and circuits. In doing this, it aims to establish an inimitable technology structure for spintronics logic integrated circuits and to demonstrate the high performance of spintronics logic integrated circuits at ultra-low power that far surpasses the conventional levels.

Paradigm shift in logic integrated circuits - the brain of information devices Logic integrated circuit, where intelligent systems are integrated on a single chip die, is the key technology in modern society, determining the quality of various systems as well as the social infrastructure. Ground-breaking innovation that forces paradigm shift now rarely occurs in the designing and manufacturing technologies of VLSI which have already seen tremendous growth. However, based on the achievements of past projects, it has become evident that the fusion of nonvolatile spintronic devices which retain memory without energy usage with the semiconductor integrated circuits will bring about a revolutionary change. This fusion will realize new integrated computing systems with high performance and ultralow power consumption that dramatically exceed conventional levels. Research areas of our program span from materials development to device realization, integration, design tool development, designing new systems, and demonstration of the low-power high-performance integrated systems. Through our research activities, the program seeks at assuming a leading role in achieving the innovative change by the fusion of spintronic devices and logic integrated circuits and purposes to play a pivotal role in the world-wide innovation cycle of logic VLSIs.
Spintronics: Research area to develop innovative materials and devices with novel functions by exploiting the two properties of an electron: charge (property of causing electrical phenomena) and spin (property of producing magnetism).


From basic to applied, and back I have been working on basic research on spintronics in the area of magnetic semiconductors, triggered by the curiosity of what would happen if the semiconductors for transistors and lasers were made magnetic. Through the research we accumulated knowledge of manipulating magnetism by electrical means, namely by electrical current and filed. This forms the basis of our program; to verify that the fusion of advanced spintronic devices and semiconductor integrated circuits would realize ultra-low power high performance logic integrated circuits, the brain of information devices. We are working with researchers around the world in the R&D of materials, devices, and circuits. These worldwide efforts eventually stimulate and seed the next generation basic research.
