In recent years, Parkin has shifted emphasis from static hard drive storage devices to dynamic memory technologies and is currently developing an innovative chip called MRAM. Based on a tiny, checkered grid of magnetized switches, magnetic random-access memory will eventually replace dynamic random-access memory (DRAM), the ubiquitous workhorse in almost all the 320 million PCs currently in use.
The crucial difference between MRAM and DRAM is that Parkin's chip operates without electricity, relying on magnetic polarity to store data. This distinction has important consequences for, among other things, a computer's boot-up time, which may explain why Parkin is in a hurry. He's on his way to delivering something that's very high on the wish list of PC users everywhere: "instant-on" computers.
[...] Replace DRAM with MRAM, and your computer would work like other electronic devices: Flip the power switch on, and the machine is up and running immediately. When you switch off your PC, an MRAM chip would retain anything loaded on it, such as the OS and apps.
Het duurt alleen waarschijnlijk nog jaren voodat we deze technologieŽn in onze computers of MP3 spelers zullen zien .
