Some guys from the National Institute of Advanced Industrial Science and Technology and the University of Tokyo claim that they’ve developed techniques to make flash chips a bit more robust.
Current flash chips have about a finite lifetime of reads & writes due to the design of the technology. As the chip sizes get smaller, this number drops quickly. This makes the life spans of SSD based hard drives in particular a bit worrisome.
Using nano sized ferroelectric cells they are able to reach a much higher density of cells on individual chips. This allows not only increased reliability at a smaller scale, but also lets wear leveling work better as a larger portion of cells can be isolated as they fail.
Of course the biggest leap is that the nano ferroelectric cells are much more energy efficient, using under a third of the power, 6 volts vs the traditional 20 volts.
