Hynix says it is sampling its 96-layer Tbit  QLC ‘4D’ NAND. Hynix calls its technology 4D  because it combines 3D Charge Trap Flash technology (CTF) with Periphery Under Cell (PUC). Hynix says 96-layers gives 49% improved bit density over 72-layer 3D NAND products. Hynix plans to develop a QLC software algorithm and controller and launch its ...
