New chip: processor and memory combined
Japanese researchers at Tohoku University in Sendai have succeeded in developing a chip that could revolutionize the production of processors to date. The chip is called 'Spintronic' and can process data as well as store it magnetically.
This is currently only possible at minus 250 degrees Celsius and a voltage of 125 volts. The semiconductor consists of an iridium-manganese-arsenide alloy. It will therefore take a few years before the chip is ready for series production. An electrical pulse switches a magnetic field in the semiconductor either on or off so that the chip can be switched between CPU and memory. Unfortunately, this effect is currently not possible under normal conditions.
