Road to the Development of an Instant-on PC

01.02.2011
Development of novel transistor with combined logic and memory functions with power consumption reduced to one-millionth that of conventional devices.

A group headed by Dr. Tsuyoshi Hasegawa, a Principal Investigator at the International Center for Materials Nanoarchitectonics (MANA; Director-General: Masakazu Aono), National Institute for Materials Science (President: Sukekatsu Ushioda), in joint research with a research group under Prof. Takuji Ogawa of the Graduate School of Science, Osaka University, and a research group under Prof. Shu Yamaguchi of the Graduate School of Engineering, The University of Tokyo, succeeded in the development of a novel transistor, the gatom transistor,h which performs both logic and memory functions while reducing power consumption to 1 x 10-6 that of the conventional devices.

Logic elements which are capable of retaining their state (i.e., memory) will be indispensible for the development of instant-on personal computers (PC) and other electronic equipment. The development in this work is expected to accelerate the realization of these devices.

In contrast to conventional transistors, which control the movement of electrons in a semiconductor, the newly-developed gatom transistorh operates by transferring a very small amount of metal atoms in an insulator. By using an insulator, which has higher resistance than a semiconductor, as the base material, and realizing on/off states by transfer of a tiny amount metal atoms in this material, the new device achieves a high on/off ratio on the same level as conventional semiconductor transistors with extremely low power consumption. Furthermore, it was found that the gatom transistorh also operates as a memory element which retains states by control of the operating voltage range.

As non-volatile logic circuits, which reconfigure circuits corresponding to computational results, are able to retain their state even when the power supply is turned off, high expectations are placed on the developed device as a new type of computer circuit for realizing PCs with zero starting time. Conventionally, one glogic element with memoryh was formed by combining a logic element (transistor) and a memory element (memory). However, with the conventional devices, the power consumption required for memory is extremely high, and low power consumption, in which memory power requirements are greatly reduced, had been considered necessary for practical application. The gatom transistorh developed in this research reduces the power consumption required for memory to 1/1,000,000 that of the conventional technology. In addition, because it possesses both logic and memory functions, it is expected to contribute to the realization of neural computing systems.

This research was carried out as part of the research topic gDevelopment of Atom Transistorh (Research Representative: Tsuyoshi Hasegawa) in the research area gResearch of Innovative Material and Process for Creation of Next-generation Electronics Devicesh (Research Supervisor, Dr. Hisatsune Watanabe, President & CEO, Semiconductor Leading Edge Technologies, Inc.), Core Research of Evolutional Science & Technology, Team-based Basic Research (CREST) of the Japan Science and Technology Agency (JST). These results were published online by the scientific journal gApplied Physics Express (APEX)h on December 24, 2010.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
