While we've recently seen the introduction of 19 nm NAND memory, manufacturers are already preparing for 16 nm NAND. The NAND flash memory is used in e.g. SSDs and smaller memory means more chips per wafer thus lower production costs. Smaller chips also introduce new challenges, as the density increases the chips are more error prone. Improved error correction methods are required to make the data on the chips reliably available.
While it's expected that the first chips will be available in 2013, due to the challenges ahead, mass production of the chips will be later than expected. But according to Digitimes this will help chip prices to become more stable allowing downstream module companies to focus on developing new products and applications
