TLC NAND flash memory is already available on the market but so far it has limited success. This new type of flash memory promises to be more cost-effective than MLC NAND flash memory but has a much lower durability.
“Initial applications for our 16nm TLC components will be more consumer and retail oriented upfront,” said Marc Durcan, chief executive officer and president of Micron. “To-date no one has had a lot of success even on the client side enabling TLC memory. There is a lot of work being done […] around controller development […] because I think that is where the error correction and capabilities around enabling TLC to be reliable enough to ship in [the SSD] segment. But we still think that is kind of a 2015 calendar year phenomenon, we do not see that happening in large scale in calendar ‘14.”Source KitGuru
