Column: From 3D NAND to 3D DRAM — how vertical stacking is reshaping memory chip manufacturing
After 2013, planar NAND flash memory began reaching its scaling limits at the 15–16nm process...acute with the adoption of triple-level cell (TLC) NAND, which requires precise threshold-voltage detection....planar scaling increasingly difficult.
