According to SK Hynix's official website, on August 29, SK Hynix announced that it had successfully developed the world's first 16Gb DDR5 DRAM using the sixth-generation 10-nanometer (1c) process. It will complete the preparation for mass production of 1c DDR5 DRAM within the year and start supplying products from next year, leading the development of the semiconductor memory market.
It is reported that SK Hynix developed the 1c process in the form of an expansion of the 1b DRAM platform, which can not only reduce the trial and error that may occur during the process of process sophistication, but also retain the advantages of high performance. In addition, new materials have been developed and applied in some EUV processes, and EUV applicable processes have been optimized throughout the process to ensure cost competitiveness. At the same time, design technology innovations have also been made in the 1c process, and its productivity has increased by more than 30% compared with the previous generation 1b process.
According to reports, the 1c DDR5 DRAM will be mainly used in high-performance data centers, and its operating speed is 8Gbps (8 gigabits per second), which is 11% faster than the previous generation. In addition, energy efficiency has also increased by more than 9%. With the advent of the AI ??era, the power consumption of data centers continues to increase. SK Hynix said that if global customers operating cloud services adopt SK Hynix's 1c DRAM in data centers, the company predicts that their electricity bills can be reduced by up to 30%.
SK Hynix emphasized that as the 10-nanometer DRAM technology is passed down from generation to generation, the difficulty of fine processes has also increased, but it has improved the design completion based on the fifth-generation (1b) technology that has been recognized for its highest performance in the industry, and has taken the lead in breaking through the technological limits. Kim Jong-hwan, vice president of DRAM development at SK Hynix, said: "The 1c process technology has both the highest performance and cost competitiveness. The company will apply it to the most advanced DRAM main product groups such as the new generation HBM1, LPDDR62, and GDDR73, thereby providing differentiated value to customers."
