The AI boom’s appetite for DRAM has reached Apple’s supply chain weeks before the iPhone 18 launch. Semiconductor analyst Tim Culpan reports that roughly $1B of A20 Pro processors sit unpackaged at TSMC because the memory needed to complete them has not arrived, with the first foldable iPhone and the iPhone 18 Pro expected to debut in less than six weeks.
Apple’s first 2nm chip, built on TSMC’s N2 process, has been shipping in volume with strong yields since earlier this year. But chip packaging pairs the processor with its memory, and the missing DRAM has frozen that step. Any slippage in packaged chip deliveries would squeeze final assembly at Foxconn and BYD in China, even if Apple locks in enough memory for launch day.
The logjam stems from AI data center buildouts absorbing global DRAM output. Micron supplies most of Apple’s mobile memory, with SK Hynix and Samsung filling the rest, and CEO Tim Cook told investors on July 30 that supply constraints are significant and flexibility is limited.
Bloomberg says the squeeze has already forced price rises and is shifting buyer attention to the MacBook Pro at the expense of the MacBook Air. Supply partners say Apple is planning around 200 million handsets across the iPhone 18 family over its lifetime. Insiders expect Apple to hit initial demand, but warn online order wait times could lengthen as retail stock runs thin.
