Mram could one day overthrow hard discs and flash memory

BBC says : magnetoresistive random-access memory or Mram could one day overthrow hard discs and flash memory

A couple of weeks ago a company called Freescale announced that it had produced a working Mram chip which can hold four-megabits, that is about half a megabyte.

It is very small compared to the Ram and flash chips on the market, but it is a start.

In fact many companies, including IBM, have been working on the nanotechnology behind Mram for around a decade.

Put simply, Mram stores data magnetically, in the same way a hard drive does. This makes it non-volatile.
