DRAM shortage strands $1B in Apple chips at TSMC

A global DRAM supply crunch has left approximately $1 billion worth of Apple ↘ 0.80% processor wafers stranded at TSMC Taiwan Semiconductor Manufacturing Company Limited ↘ 1.20%, unable to complete final packaging due to insufficient memory supply, according to multiple reports this week.

Chips Piling Up as Memory Runs Dry

The A20 Pro processors, destined for Apple's upcoming iPhone 18 Pro lineup, have completed wafer fabrication but cannot proceed to advanced packaging because the process requires matching DRAM components that are in critically short supply. TSMC's Fab 3 in Longtan, Taiwan, which handles the new Wafer-Level Multi-Chip Module Packaging process, is where the bottleneck has formed.tradingkey+1

Semiconductor journalist Tim Culpan first reported on August 4 that Apple and its suppliers are "scrambling to get enough memory chips" with less than six weeks until the expected debut of the iPhone 18, iPhone 18 Pro, and the foldable iPhone Ultra. Apple relies primarily on Micron ↘ 2.22% for DRAM but also procures from SK Hynix ↘ 3.12% and Samsung.culpium

AI Demand Squeezes Consumer Supply

The shortage stems from a structural reallocation of memory capacity toward artificial intelligence applications. Major DRAM manufacturers have prioritized high-margin High Bandwidth Memory and server DRAM to meet surging demand from AI infrastructure buildouts, squeezing supply available to consumer electronics. Nvidia ↘ 1.47% and AMD Advanced Micro Devices, Inc. ↘ 1.47% orders have kept TSMC's CoWoS advanced packaging capacity consistently tight, and memory constraints are now extending that pressure to Apple's orders.tradingkey

According to WCCFTech, Apple has attempted to negotiate with current suppliers and even explored a partnership with Chinese manufacturer CXMT to procure shipments at lower prices, but these efforts have been unsuccessful.wccftech

iPhone 18 Launch at Risk

The packaging delays raise the prospect of supply constraints when Apple unveils its new iPhone lineup, expected in September. Computerworld reported that the A20 processors are "reportedly piling up while manufacturers wait" for adequate DRAM. Earlier reporting from Bloomberg's Mark Gurman had flagged that memory constraints could push certain Apple products into early 2027.macrumors+2

For consumers, the memory shortage is expected to contribute to price increases across Apple's product line, with analyst Jeff Pu of GF Securities recently projecting up to $300 in additional costs for new iPhones.computerworld
