Samsung Electronics Co. and SK Hynix Inc. are being positioned for a prolonged earnings lift as research firms and Goldman Sachs argue that AI infrastructure spending is spreading the memory boom beyond HBM (high-bandwidth memory used in AI chips) into DRAM and NAND flash. SigmaIntel said global semiconductor revenue could reach about $1.587 trillion this year, up 107% from a year earlier, with memory contributing about $960 billion, or roughly 60% of chip sales, while Omdia and Counterpoint Research also projected outsized growth. Analysts said supply is tightening because Samsung, SK Hynix and Micron Technology Inc. are diverting capacity toward HBM, pushing third-quarter DDR average selling prices to four to five times year-earlier levels and lifting demand for eSSDs (enterprise solid-state drives) used in AI servers. Counterpoint expects server products to make up 56% of memory revenue this year, up from 37% last year, and sees the upcycle running through the first half of 2027, while Omdia sees bottlenecks lasting at least through 2027. Goldman Sachs said the shortage could persist through 2030, even as competition from China's CXMT and Taiwan's Nanya Technology Corp. accelerates.
