Samsung starts mass production of industry’s first32-Layer 3D V-NAND flash memory
Samsung Electronics has begun mass producing the industry’s first three-dimensional (3D) V-NAND flash memory using 32 vertically stacked cell layers, which is its second generation V-NAND offering. Samsung’s 32-layer 3D V-NAND – also referred to as Vertical NAND– requires a higher level of design technology to stack the cell arrays than the previous 24-layer V-NAND, yet delivers much greater production efficiency because Samsung can use essentially the same equipment it used for production of the first generation V-NAND.
In addition, Samsung has just launched a line-up of premium SSDs based on its 2nd generation V-NAND flash memory with 128 gigabyte (GB), 256GB, 512GB and 1TB storage options. After introducing 3D V-NAND-based SSDs to data centers last year, Samsung is now extending its V-NAND SSD line-up to high-end PC applications, in expanding its market base. The new 3D V-NAND-based SSDs have approximately twice the endurance for writing data and consume 20 percent less power, compared to planar (2D) MLC NAND-based drives.
