FAQs
No. SK hynix is an independent company, part of the SK Group, competing with Samsung in the memory chip market.
Often tied to memory chip market cycles (oversupply → price drops), macroeconomic trends (weak demand), or tech industry slowdowns.
High R&D costs for advanced memory tech, supply – demand swings (shortages raise prices), and its premium position in high – performance chips.
In specific segments (e.g., certain DRAM niches) it competes closely, but Samsung remains a top rival; overall market leadership varies by category.
Primarily self – fab or uses partner foundries for some processes, but TSMC isn’t a core supplier (focus on in – house/strategic partners).
