In Jinjiang, Fujian, a Storage Super Unicorn Lies Quiet
In Fujian's Jinjiang, a city known for sportswear, lies a quiet semiconductor giant: Fujian Jinhua Integrated Circuit Co. (JHICC). Once a promising domestic DRAM manufacturer alongside Yangtze Memory and ChangXin Memory Technologies (CXMT), its journey was derailed in 2018 when the U.S. placed it on an Entity List and filed criminal charges for alleged trade secret theft. This halted production for years.
A turning point came in February 2024 when a U.S. federal court found JHICC not guilty. However, it had lost crucial time. While CXMT soared to become a top-valued A-share company in 2024, JHICC, with an estimated valuation of 80 billion RMB, was just restarting. Its current output is primarily customized DDR4 chips, not the advanced DDR5/HBM demanded for AI, but it still benefits from the broader memory chip upcycle.
JHICC's story is tied to Chen Zhengkun, a veteran engineer who left Micron to lead the venture. Founded in 2016 with state-backed funding, JHICC partnered with Taiwan's UMC to develop DRAM technology. Rapid progress was cut short by the U.S. actions, which Micron initiated, partly due to its heavy reliance on the Chinese market.
Post-sanctions, Chen's team worked to rebuild the production line with reduced reliance on U.S. technology. According to its records, JHICC achieved small-scale production and revenue growth under immense pressure. It now focuses on the stable "niche" DRAM market (e.g., TVs, routers) with a monthly capacity of ~40,000 wafers, aiming for 60,000 by 2026. It holds over 1,000 patents but remains on the Entity List.
For Jinjiang, investing in JHICC was a bold industrial leap. The local government provided unwavering financial and logistical support during the crisis, helping the company survive. JHICC has become the anchor for a growing local semiconductor cluster.
Though its scale lags behind domestic peers, JHICC's persistence symbolizes a hard-won foothold in a global market long dominated by Samsung, SK Hynix, and Micron. Having missed one boom, it seeks a place in the new AI-driven memory supercycle.
