Hello,
3D NAND is a type of non-volatile flash memory in which the memory cells are stacked vertically in multiple layers. The design and fabrication of 3D NAND memory is radically different than traditional 2D -- or planar -- NAND in which the memory cells are arranged in a simple two-dimensional matrix.
3D NAND flash stacks memory cells vertically in multiple layers, achieving a higher density than traditional NAND memory. It can be used in the same situations as traditional NAND and has a number of advantages over hard disk and tape storage.
Hope this helps
Thanks
