Memory chip stocks are rallying in the pre-market session, driven by a rebound in Asian memory giants SK Hynix and Samsung following a recent sell-off. A positive report from research firm SemiAnalysis on SK Hynix's DRAM pricing and profitability is also fueling the upward momentum. This recovery is occurring within the context of a broader memory 'supercycle,' characterized by strong demand and tight supply for DRAM and NAND chips, largely due to the expansion of AI infrastructure.
