Since 2006, many of new 3D NAND Flash cells have been proposed and commercialized on the market. Already, we have seen 3D NAND cell structure up to 64L/72L with single or multi-stack NAND string architecture. The memory density on Micron/Intel’s 64L 3D NAND 256 Gb/die reached 4.40 Gb/mm2 (256 Gb/die). In this session, we’ll overview 3D NAND Flash roadmap, products, cell design, structure, materials and process integration. The 3D NAND cell architecture from major NAND manufacturers including Samsung TCAT V-NAND, Toshiba/Western Digital BiCS, SK Hynix P-BiCS and Micron/Intel FG CuA will be reviewed and compared. Current and future technology challenges on 3D NAND will be discussed as well.

    Thank you for today’s Webinar.
    I am looking for the PDF version of your presentation from this web site, and it does NOT appear anywhere. Can you help me locate the site where I can retrieve the presentation material in PDF?

    Thank you.
