Toshiba QLC 3D NAND squeezes a fourth bit into flash cells
by from Techreport on (#2V5W7)
Data density is critically important to manufacturers of flash storage chips. Increasing the number of bits in a given amount of die space allows for reduced manufacturing costs, potentially lower power requirements, and gets large amounts of information into ever-shrinking packages. Flash memory comes in flavors with a single bit per cell (SLC) to three bits per cell (TLC), and now Toshiba has announced that it has started manufacturing quad-level cell (QLC) 3D NAND chips. Like it says on the tin, these chips are capable of holding four bits per cell.
