What would be lovely is a type of memory which is both fast to write, and non-volatile. So, along comes something called magnetoresistive random access memory or Mram.
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. It is also very quick, and does not wear out over time. So it seems to have the advantages of both RAM and flash, with none of the disadvantages.
