You may know that up until now NAND flash has been a planar technology. But just as with SoC processes where we have had to go vertical to FinFETs, NAND flash has reached the limitations of scaling in the 20nm nodes and is also going vertical. It is not just a lithography issue but there are also reliability and voltage scaling issues.… Read More
