International Memory Workshop: 3D NAND Flash to Reach 140 Layers By 2021
3D NAND has been one of the most important new technologies in allowing for greater storage density in space-constrained hardware (isn't that always the case, though?) As we've stepped away from the usual 2D NAND to the nowadays market-leading 3D solutions, which stack layers of memory one on top of the other (thus making use of vertical space instead of the usually more costly horizontal one), memory density and price per GB has been steadily declining - a relationship that isn't quite as parallel as it may seem, but still occurs.
