Overview
- Reports published over the past week say Apple has been testing DRAM chips from ChangXin Storage for iPhone and MacBook models and has held preliminary supply talks aimed at devices sold in China.
- Those talks have not yet produced a deal because ChangXin is seeking prices at or near Samsung and SK Hynix levels, creating friction with Apple's cost targets.
- Analyst Ming‑Chi Kuo has said Apple is trimming 2026 shipment plans for several products including higher-end iPhone and Mac models because limited DRAM is constraining production.
- Memory makers are diverting capacity to AI datacenter contracts, which pay more and reduce the chips available for consumer devices, deepening the shortfall Apple faces.
- ChangXin has posted rapid revenue and profit growth and is now seen as a top-four DRAM maker, but Apple still faces technical qualification, price and supply-risk questions before it could shift meaningful volume to the supplier.
