Macronix Develops Self-Healing NAND Flash
Researchers at Taiwanese company Macronix have proposed a solution that will allow NAND flash to bypass the degradation that results from programming and erasing the memory thousands of times. The team had previously found that NAND flash could be returned to a "good" state but it would require "heating for hours at around 250°C" The new technique would achieve similar results by heating groups of memory cells to 800°C for a brief period using onboard heaters. The results of their research are being presented at the IEEE International Electron Devices Meeting in San Francisco, California from December 10-12. If this technique can be refined and placed into commercial solid state drives, it would have a tremendous impact on the reliability and lifespan of these storage devices.
