Data writing in the spintronics element increases power consumption in a high-speed electronic circuit with an operating frequency in excess of 400 MHz. However, Tohoku University and NEC successfully decreased the power consumption required by writing to one tenth. The two organizations developed a technology to increase the operating speed of an LSI electronics circuit capable of eliminating standby electricity 1.5 times to 600 MHz by eliminating unnecessary data rewriting, using the nature of an element containing data that does not write data unless a certain amount of current is added. They plan to complete the technology to materialize a low-power LSI that consumes power only at the point of use toward 2013.
A research team led by Professors Tetsuro Endo and Hideo Ohno of Tohoku University developed this technology in alliance with NEC in a project sponsored by the government. The research members increased the speed of a hybrid circuit that merges the spintronics element and the complementary metal-oxide semiconductor. They increased the operation speed and decreased the power consumption required for writing by decreasing the number of writing frequencies considerably. In the future, they wish to realize a system LSI without standby electricity by incorporating the hydride circuit in the memory and central processing unit.
