Developments in Spintronics

Modern digital electronics owe their simplicity to measuring an electron's charge to determine either a @0@ or @1@ state. But that comes at a cost in terms of speed and power consumption. Spintronics is a similar manner of determining binary state but it uses the up or down spin of an electron as a discriminator. The technology has already been used in magnetic hard drives as a manner of using alternate physical materials, using less power, and measuring the state faster all as a means of increasing data density and throughput speeds. Now, the technology is under evaluation for use in MRAM and even CPU caches where it is hoped to achieve power efficiency savings upwards of 80%.
