Internationally, South Korea’s Samsung Electronics and SK hynix have been pursuing the 4F² technology.
SK hynix unveiled its 4F² road map in 2025, while Samsung planned to mass-produce sub-10-nanometre DRAM based on the new design by 2028, according to a report published by Seoul Economic Daily on October 13.
CXMT said it was the first company to complete engineering sample validation of the architecture, and if development continues smoothly, it could become the first company globally to bring 4F²-based products to market.
