Demand for high-bandwidth memory (HBM) is crowding out production capacity for consumer memory. Despite capacity expansions by major memory makers, including Micron, Samsung, and SK Hynix, the supply of HBM for AI servers remains tight, and the demand from large chipmakers is difficult to satisfy immediately. IC distributors report that lead times from memory manufacturers have now extended to 52 weeks. With priority allocation given to large clients, almost no stock is available. Both distributors and customers must now pay upfront and wait in line for delivery.
