3D NAND flash memory The first 3D NAND flash memory started shipping in 2013 with 24-layers. The revolutionary process introduced a chemical vapor deposition (CVD) process to stack thin film layers connected with precise holes etched through the entire vertical structure. Through the years, the ne...
Before the introduction of 3D NAND technology, NAND flash memory options were all 2D or planar. However, we’re now reaching the physical limits of what can be achieved on a 2D plane. Unlike 2D NAND where memory cells are crammed into a limited space on a chip, 3D NAND stacks the memor...
