Changxin Storage announces the launch of 4F ² architecture storage chips by the end of the year, causing a decline in the stock prices of Samsung and SK Hynix

Changxin Storage President Cao Kanyu announced that the company will launch a new generation of data center server storage chips using a 4F ² architecture before the end of the year. This technology reduces leakage by vertically surrounding gate stacked transistors, and Changxin Memory's market share in DRAM has increased from 4% in the same period last year to 10% in the second quarter of this year. Affected by this news, Samsung and SK Hynix fell more than 7% in the Korean stock market, while Micron closed down 4% (source: Bloomberg).
