Apple Faces iPhone 18 Delays Amid Global Memory Shortage

A global shortage of mobile DRAM is creating a critical supply chain bottleneck for Apple Inc., threatening the production of the iPhone 18, iPhone 18 Pro, and the foldable iPhone Ultra. The crisis is driven by a shift in wafer capacity toward High Bandwidth Memory (HBM) for AI servers and intense demand from Chinese firms like Huawei and Xiaomi. Current primary suppliers, including Micron Technology, SK Hynix, and Samsung Electronics, have reportedly sold their capacity through 2027.

At TSMC, the shortage has stalled the final assembly of A20 Pro and C2 processors. While TSMC has successfully ramped up its 2nm (N2) process, processors cannot move to the Wafer-Level Multi-Chip Module (WMCM) packaging stage without memory chips. Consequently, TSMC is holding approximately $1 billion worth of Apple wafers. These constraints have already delayed MacBook Air shipments until September and may lead to stock shortages or launch delays for the iPhone 18 Pro and Pro Max.

To mitigate the risk, Apple attempted to secure LPDDR5X memory from Chinese manufacturer ChangXin Memory Technologies (CXMT). However, CXMT refused to grant price discounts, insisting on standard market rates. While Apple is currently absorbing some costs through higher margins and new leasing services in the United States, analysts predict iPhone prices could increase by up to $300. The Global Electronics Association reports that 62% of all electronics manufacturers are experiencing similar constraints, suggesting a long-term industry-wide crisis.
