Samsung Reportedly Ramps 4nm Capacity For Memory Chips, Stepping Up Competition With SK Hynix, Micron
Samsung Electronics plans to expand its 4nm foundry capacity to meet rising demand for next-gen memory chips, intensifying competition with SK Hynix and Micron. The company expects HBM4 revenue to triple sequentially in Q3, with HBM4 accounting for over 60% of its total HBM revenue in the second half. Samsung's HBM revenue share rose to 33% in Q2 from 21% in Q1, according to Counterpoint data.
