] Gallagher said there are a number of advantages to ] MRAM, the first of which is that it uses magnetic— ] rather than electronic—charges to store bits of data. ] This is done by controlling the spin of captured ] electrons. According to Gallagher, this technology ] could lead to portable devices that not only can ] store more data, but also access it faster, all the ] while using less battery power. ] Also, unlike electronic memory chips, the non-volatile ] MRAM chips can retain data even when power to the device ] is turned off. That means that PCs and other computers ] could boot up immediately similar to turning on a light ] switch, Gallagher said rather than having to wait for ] software to load up. That also will save power, since a ] device does not need a constant flow of power to keep the ] data intact. |
