Apple: $10 Billion in Chips Stuck Due to DRAM Shortage

Apple, the world's most valuable company, faces a problem that no check can solve: the global DRAM memory shortage. According to an exclusive by journalist Tim Culpan, production of the A20 Pro processor, destined for the iPhone 18, is partially halted. TSMC, Apple's contracted manufacturer, has accumulated silicon wafers worth $1 billion (a figure that could rise to $10 billion across the supply chain) waiting for the necessary DRAM to complete packaging.

What exactly happened?

The problem lies in TSMC's new WMCM (Wafer-Level Multi-Chip Module) packaging process, which integrates the processor and DRAM memory on the same substrate. This technique, which improves performance and reduces consumption, is Apple's choice for its A20 Pro chip. However, the global DRAM shortage, exacerbated by the rise of artificial intelligence, has caused TSMC to be unable to complete the process: the wafers with the SoC are ready, but there is no memory to integrate.

Tim Culpan, in his newsletter, states: "A20 Pro production on N2 is going well, with good volume and good manufacturing yields. However, wafers are piling up waiting for DRAM before they can be packaged and move to the next phase." This situation directly affects the launch schedule of the iPhone 18, planned for September 2026.

Why is it important?

This setback is not a simple logistical delay; it is a symptom of a structural problem in the semiconductor industry. DRAM memory demand has skyrocketed due to generative artificial intelligence, which requires large amounts of high-bandwidth memory (HBM) for data centers. Memory manufacturers, such as Samsung, SK Hynix, and Micron, have prioritized HBM production, neglecting conventional DRAM used in mobile devices.

Apple, despite its bargaining power, is not immune to this dynamic. The company depends on a few suppliers for a critical component, and when the market tightens, even tech giants suffer. This episode recalls the chip supply crisis of 2021-2023, although then the bottleneck was in wafers, not memory.

Impact on iPhone 18 and Apple

The most immediate consequence is a possible delay in the launch of the iPhone 18, especially the Pro models, which would mount the A20 Pro. Apple could be forced to delay the availability date or initially launch only models with the previous chip. Additionally, DRAM costs have increased, which could raise the final device price or reduce Apple's margins.

On a strategic level, this problem underscores Apple's need to diversify its supply chain and reduce its dependence on TSMC and memory manufacturers. The company is already working on its own modems and packaging technology, but DRAM remains a critical component that it cannot manufacture internally.

What should readers know?

• It's not an Apple-exclusive problem: the entire mobile industry faces the DRAM shortage, although Apple, due to its volume, is the most affected.
• Smartphone prices could rise: the memory shortage and increased costs could be passed on to the end consumer.
• AI is the underlying cause: the rise of artificial intelligence is diverting memory production to data centers, leaving less capacity for mobile devices.
• The iPhone 18 could be delayed or have limited stock: Apple might prioritize Pro models and delay standard models, as it has done in the past.

Comparisons with previous events

This incident recalls the chip shortage of 2021, which affected the entire automotive and electronics industry. It is also similar to the problem Apple faced with Intel's 5G modem in 2018, which led it to adopt Qualcomm modems and later develop its own modem. In both cases, the lesson is the same: dependence on a single supplier or technology can have serious consequences.

The immediate future

Apple and TSMC are working to mitigate the problem. According to Culpan, Apple is "doing everything possible" to secure DRAM supplies, but the situation could last until 2027. Meanwhile, investors and consumers should watch for official Apple announcements about the iPhone 18 launch date.

In summary, the problem of $10 billion in stuck chips is a reminder that even the Cupertino giant is not exempt from the ups and downs of the semiconductor market. The DRAM shortage, driven by AI, is a crisis affecting the entire industry and will likely have consequences on the prices and availability of upcoming smartphones.
