BBC reports: "A microchip which can store information like a hard drive has been unveiled by US company Freescale. ... The chip, called magnetoresistive random-access memory (Mram), maintains data by relying on magnetic properties rather than an electrical charge."
This technology is the is the most significant development in computer memory for about a decade. The advantages of MRAM vs. Flash is: MRAM has faster read/write speeds and data doesn't degrade over time.
