SK Hynix has announced the company completed recently the development of enterprise SATA SSDs built using its 72-layer 512Gb 3D NAND flash chips. SK Hynix combined the 72-layer 512Gb 3D NAND flash with its in-house developed firmware and controller to provide the maximum density of 4TB, and makes the most of its 72-layer 512Gb 3D NAND chips to double the biggest density of the SSD of the same size with 256Gb NAND chips. A single 4TB SSD could contain 200 UHD (Ultra-HD) movies, each of which is generally as large as approximately 20GB, according to the vendor. The new eSSD supports sequential read and write speed of up to 560MB/s and 515MB/s, respectively, and can perform 98,000 random read IOPS (input/output operations per second) and 32,000 random write IOPS. SK Hynix also improved the esSSD read latency.

SK Hynix has started full-scale mass production of 16nm 64-gigabit (Gb) MLC NAND flash chips, according to the South Korea-based memory chipmaker. SK Hynix entered mass production of its first-version 16nm NAND flash in June, and has recently started to mass produce the second version which is more cost competitive due to its smaller chip size, the company said. SK Hynix has also developed 128Gb (16-gigabytes, 16GB) MLC chips based on the specification and endurance of 16nm 64Gb MLC, with mass production scheduled for early 2014, the company noted.

SK Hynix has developed 6Gb low-power DDR3 (LPDDR3) using 20nm-class process technology. This product is a high-performance mobile memory solution that features low power consumption and high-density, ideal for premium mobile devices, according to the chipmaker. Four 6Gb LPDDR3 chips can be stacked up and realize a high density of maximum 3GB solution in a single package. In consequence, this package reduces the operating power as well as the standby current by 30% and the height of the package becomes thin compared to SK Hynix' 4Gb-based one. In addition, it works at ultra low-voltage of 1.2V thus it satisfies low power consumption which mobile applications demand, according to the vendor. The SK Hynix 6Gb LPDDR3 works at 1866Mbps, and with a 32-bit I/O it processes up to 7.4GB of data per second in a single channel, and 14.8GB in a dual channel. It can be provided in a form of package-on-package (PoP) to mobile devices.
