Sticking with the theme of new types of flash memory, a story appeared on Slashdot about Anobit Technologies, a company working on a new type of MLC flash that should have the wearability of SLC.  This could be a dangerous area to focus research on as the major benefit of MLC is how incredibly cheap it is compared to SLC memory, though it is hard to call either type affordable without wincing at least a little.  This is important as there has been no mention of price, only information on the technology its self.  Increasing the lifetime of MLC tenfold is a great thing, but if the memory ends up with a price tag similar to SLC it will not be able to push the other types of MLC storage out of the market.

“Anobit Technologies announced it has come to market with its first solid state drive using a proprietary processor intended to boost reliability in a big way. In addition to the usual hardware-based ECC already present on most non-volatile memory products, the new drive’s processor will add an additional layer of error correction, boosting the reliability of consumer-class (multi-level cell) NAND to that of expensive, data center- class (single-level cell) NAND. ‘Anobit is the first company to commercialize its signal- processing technology, which uses software in the controller to increase the signal-to- noise ratio, making it possible to continue reading data even as electrical interference increases.’ The company claims its processor, which is already being used by other SSD manufacturers, can sustain up to 4TB worth of writes per day for five years, or more than 50,000 program/erase cycles — as contrasted with the 3,000 cycles typically achieved by MLC drives. The company is not revealing pricing yet.”
