Creating non-volatile electronics by spintronics technology

- Toward developing ultimate green IT devices-

Abstract

We have been promoting Full Research to develop ultimate green IT devices based on non-volatile electronics. A core technology of non-volatile electronics is a non-volatile memory possessing features such as large capacity, high-speed operation, and high endurance. To develop such an ultimate non-volatile memory, we developed a novel high-performance magnetic tunnel junction device based on magnesium oxide (MgO) and the underlying mass-manufacturing technology. This technology has already been commercialized for the production of the magnetic heads of ultra-high density hard disk drives (HDD). Now we are also performing intensive R&D activities for developing the ultimate non-volatile memory called Spin-RAM.
