Comparing Figure 11a with 11b, the Vt shift looks much more obvious for the 3D NAND compared to 2D 2y FG.

In their 2009 paper, they did 16 layers as 2X8, not all at once. More alternating layers makes a multilayer more optically reflective, basic physics.

Doesnt Toshiba think they can do 16 layers?

Not sure if that is after or before you put a U-bend in the channel.

If before, then 8 layers can produce 16-bit NAND flash words on single vertically connected string.

Still many issues related to reliability, an extra dimension for disturbance, as well as the difficulty of etching straight and deep. Even lithography cannot escape difficulty. How can you align to the substrate through a just-deposited multilayer?
