Nanowires could be used to significantly boost conventional RAM, resulting in computers that are ready the minute you turn them on, and don't lose data when the power fails, says a US researcher.
Dr Stuart Parkin, an IBM research fellow based in San Jose presents his research on "racetrack memory" this week at the International Conference on Nanoscience and Nanotechnology in Sydney.
"You would never have to save your data or reboot your computer," says Parkin.
Current computers use solid state RAM to process data, but store data as magnetised regions on a hard disk drive.
The problem is, says Parkin, while hard disks are relatively economical, they are slow and unreliable.
It takes time for the disk to rotate to a point where data can be read or written. This is one of the reasons why it can be slow for a computer to boot up, as it loads the software from the hard disk into the RAM.
The reading and writing gadget can also crash the disk causing catastrophic damage, and if the power fails, information in the RAM that has not been saved to the hard disk is lost.
