Samsung's 3D V-NAND Flash Memory Enters Mass Production

Samsung Electronics has begun mass production of the industry’s first 256-gigabit, three-dimensional (3D) Vertical NAND (V-NAND) flash memory based on 48 layers of 3-bit multi-level-cell (MLC) arrays for use in solid state drives (SSDs).

Samsung’s new 256Gb 3D V-NAND flash doubles the density of conventional 128Gb NAND flash chips. In addition to enabling 32 gigabytes (256 gigabits) of memory storage on a single die, the new chip will also easily double the capacity of Samsung’s existing SSD line-ups, and provide an ideal solution for multi-terabyte SSDs. A 48-layer 3-bit MLC 256Gb V-NAND flash chip delivers more than a 30 percent reduction in power compared to a 32-layer, 3-bit MLC, 128Gb V-NAND chip, when storing the same amount of data.

“With the introduction of our 3rd generation V-NAND flash memory to the global market, we can now provide the best advanced memory solutions, with even higher efficiency based on improved performance, power utilization and manufacturing productivity, thereby accelerating growth of the high-performance and the high-density SSD markets,” said Young-Hyun Jun, President of the Memory Business at Samsung Electronics. “By making full use of Samsung V-NAND’s excellent features, we will expand our premium-level business in the enterprise and data center market segments, as well as in the consumer market, while continuing to strengthen our strategic SSD focus.”
