HK Stock Market Move | CMOC Group Limited (03993) rose more than 10% in early trading. SK Hynix is attempting to use molybdenum instead of tungsten to improve NAND performance.

CMOC Group Limited (03993) surged more than 10% in early trading, as of press time, it rose 10.32% to HK$18.49, with a turnover of HK$771 million. On the news front, SK Hynix has completed the production verification of 375-layer NAND flash memory and is preparing to transfer its production line to the Cheongju M15 plant. The product is scheduled to be officially mass-produced by the end of this year. The technical highlight of this iteration is the use of molybdenum material to replace traditional tungsten material in the production of word lines. With the same miniaturization size, molybdenum has lower resistance, which can effectively accelerate data read and write speeds. According to Caijing, industry estimates show that Samsung's molybdenum material procurement volume was about 4 tons last year, and is expected to increase to 10 tons this year, with subsequent demand increasing year by year, reaching 80 tons by 2030. SK Hynix will begin large-scale adoption of molybdenum technology from next year, with an initial annual procurement volume of around 4 tons.
