Elpida has licensed a technology that applies the same technique used in rewriteable optical discs to non-volatile memory chips.
Developed by Ovonyx, the system, dubbed Ovonic Universal Memory (OUM), uses a thin film of chalcogenide alloy, a material similar to the substance used in DVD- and CD-RW discs. In the optical world, laser light is used to adjust the phase of the material - crystalline or amorphous - at each data-storing spot to encode the binary 1s and 0s that make up digital data. Instead of light, the Ovonyx system achieves the same result with electrical signals controlled by transistors. Read on at TheReg

"Instead of light, the Ovonyx system achieves the same result with electrical signals controlled by transistors." Is this not called RAM? Or does it still use the material found on cdrws? Either way I dont see the point of it.. |
