South Korea's storage production capacity expands again, Changxin Storage catches up and accelerates

The Zhitong Finance App learned that the Bank of Korea released a report on Friday saying that as Samsung Electronics and SK Hynix actively expand local facilities, South Korea's leading edge in memory chip production capacity is expected to expand further. The report shows that by 2028, the commissioning of a new chip factory is expected to increase South Korea's wafer production capacity by about 600,000 wafers per month. Over the same period, China's leading memory chip manufacturer Changxin Storage may increase its monthly wafer production capacity from the current 300,000 to 600,000 wafers.

Changxin Storage is building a Shanghai fab. The Bank of Korea said that as Chinese manufacturers increase their self-sufficiency rate and strengthen domestic supply chains, South Korea's market share may face increasing structural pressure in the long term.

In the field of advanced memory chips, the Bank of Korea reports that South Korea will maintain its technological advantage over the next few years.

According to reports, in June of this year, the South Korean government announced a long-term investment plan of at least 880 billion US dollars, with the participation of companies such as Samsung Electronics, SK Group, and Naver, focusing on semiconductor production capacity expansion, AI data center construction, and physical AI (physical AI) infrastructure. The common goal of the government and enterprises is to double storage production capacity within five years.

According to the latest report from market research agency Counterpoint Research, Changxin Storage reached 10% of the global DRAM market revenue in the second quarter of 2026, officially positioning itself as the fourth largest DRAM supplier in the world. In terms of leading manufacturers, Samsung Electronics continues to rank first in the global DRAM market with a 39% market share; SK Hynix's share fell to 26% from 39% in the same period last year, but its quarterly revenue still increased 214% year over year. Micron followed with a 25% share.
