Who says scientific breakthroughs never amount to anything? Everspin has followed up on research developed by IBM, TDK and German researchers years back and released the first commercial spin-torque magnotoresistive RAM (ST-MRAM) onto the market. The technology works by taking advantage of electron "spin" to store data in a magnetic, rather than electronic state, providing non-volatile memory that doesn't wear out. The company said the first chips were about 50 times the cost of flash memory by size
