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. One analyst
told the Associated Press news agency that the chip was the mo...read more

A little more info from a BBC news article:

"Unlike flash memory, which also can keep data without power, Mram has faster read and write speeds and does not degrade over time.", and "Mram chips could one day be used in PCs to store an operating system, allowing computers to start up faster when switched on."

I love that "someday" shit, don't you?

The MR2A16A is a 4,194,304-bit magnetoresistive random access memory (MRAM) device organized as 262,144 words of 16 bits. The MR2A16A is equipped with chip enable (E*), write enable (W*), and output enable (G*) pins, allowing for significant system design flexibility without bus contention. Because the MR2A16A has separate byte-enable controls (LB* and UB*), individual bytes can be written and read.
