Seoul, October 21, 2019<\/strong>
\nSK hynix Inc. (or \u2018the Company,\u2019 www.skhynix.com<\/a>) announced today that it has developed 1Znm 16Gb (Gigabits) DDR4 (Double Data Rate 4) DRAM. As 16Gb is the industry\u2019s largest density for a single chip, the total memory capacity per wafer is also the largest of the existing DRAMs.<\/p>\n

The productivity of this product has improved by about 27% compared to the previous generation, 1Ynm. It does not require highly expensive extreme ultraviolet (EUV) lithography, which gives it a competitive edge cost-wise.<\/p>\n

The new 1Znm DRAM also supports a data transfer rate of up to 3,200Mbps, which is the fastest data processing speed in DDR4 interface. The Company significantly increased its power efficiency, successfully reducing power consumption by about 40% compared to modules of the same density made with 1Ynm 8Gb DRAM.<\/p>\n

In particular, SK hynix applied a new substance not used in the manufacturing process of the previous generation, maximizing the capacitance of this 1Znm product. Capacitance, the amount of electrical charge a capacitor can store, is a key element of DRAM operation. A new design has also been introduced to increase operational stability.<\/p>\n

\u201c1Znm DDR4 DRAM boasts the industry\u2019s highest density, speed, and power efficiency, making it the best product to meet the changing demands of customers seeking high-performance\/high-density DRAM,\u201d said Lee Jung-hoon, Head of 1Z TF of DRAM Development & Business. \u201cSK hynix will start mass production and full-scale delivery next year to actively respond to market demand.\u201d<\/p>\n

SK hynix plans to expand the 1Znm technology process to a variety of applications, such as LPDDR5, the next generation mobile DRAM, and HBM3, the fastest DRAM to be.<\/p>\n
