CSPs shifted from destocking to restocking, and DDR4, due to strong demand for storage server applications, became a highlight and a long-tail product. Samsung led in market share, SK hynix had the largest revenue growth, and Micron benefited from high-capacity modules.

Key Highlights

• Revenue Growth: 2Q25 server DRAM market revenue increased by 11% QoQ, mainly driven by increased DDR5 shipments, a higher proportion of high-capacity products, and a recovery in DDR4 prices.
• Inventory Adjustment: US and Chinese CSPs continued to destock, then shifted to restocking, benefiting from capacity shifting to HBM3e, and original manufacturers also saw inventory declines.
• DDR4 Transformation: Due to its advantages in storage server applications, DDR4 demand was strong, becoming a long-tail product, expected to account for a certain percentage until 2026.
• Vendor Performance: Samsung led in market share, SK hynix had the largest revenue growth, and Micron benefited from high-capacity module demand.
• Future Outlook: AI server demand drives growth in high-capacity modules, and Chinese manufacturers are actively expanding server DDR5 products, which will impact the market.
