Intra-industry’s first 8Gb Samsung LPDDR4 mobile DRAM
Global storage industry leader Samsung Electronics announced today that has begun to intra-industry’s first 20 nm 8Gb LPDDR4 mobile DRAM.
LPDDR worldwide is perhaps the most widely used in mobile devices “working memory” memory. Brand new 20 nm 8Gb LPDDR4 memory, both in performance and integration 1 time times higher than 20 nanometer 4Gb LPDDR3 memory. In addition, the single 8Gb chip makes it possible to 4GB LPDDR4 packages, but this package was awarded the 2015 International Consumer Electronics Show (CES, Consumer Electronics Show) embedded technology innovation award. Prior to this, 2GB LPDDR3 and 3GB LPDDR3 of Samsung Electronics products already in 2013 and 2014, respectively on the CES award, this award-winning making Samsung the only one with mobile DRAM solutions enterprises won the CES Innovations Award for three consecutive years.
Because the input/output interface data transfer rate up to 3200Mbps, is commonly used in PC DDR3 DRAM twice times, new 8Gb LPDDR4 memory supports Ultra-HD video recording and playback, and can continue to take 20 million pixel HD pictures.
Compared with the LPDDR3 memory chip, LPDDR4 operating voltage is 1.1 volts, is suitable for large screen smartphones and Tablet PCs, minimum power storage solutions for high performance network systems. 2GB memory package, for example, rather than based on 4Gb LPDDR3 2GB memory chip package, based on the 8Gb LPDDR4 chip 2GB of memory because of lower operating voltages and handling speed improvement, 40% less power consumption Max. Meanwhile, new input/output signal transmission using Samsung’s unique low voltage swing Terminal logic (LVSTL, Low Voltage Swing Terminated Logic), not only further reduces power consumption of LPDDR4, and to enable chips to high frequency operation at low voltages, power efficiency to achieve the most optimal.
Samsung has started this month for global application processor vendors and mobile device manufacturers, providing respectively, based on 8Gb and 6Gb LPDDR4 2GB and 3GB LPDDR4 DRAM packaging and supplies 4GB LPDDR4 package in early 2015.
Plan quickly expanded to include the new 8Gb Samsung LPDDR4 mobile DRAM memory and server launched earlier 20-nanometer DRAM, 8Gb, DDR4 DRAM memory products production in order to better meet the needs of customers, and accelerate development of high integration of the DRAM market.
Memory chips Samsung Electronics Executive Vice President, sales and Marketing Director Cui Zhoushan said: “the volume production of 20 nm 8Gb LPDDR4 memory chip, faster than the DRAM used in PCs and servers more energy efficient. With the introduction of this product, we offer ultra high definition big-screen flagship mobile devices has contributed to the public in due course. The chip will qualify as a removable memory a big development in the history of, and its successful launch proved that our close cooperation will continue in the future and global mobile device manufacturers, common DRAM solutions optimized for next-generation mobile operating system environment. ”
