With the iPhone 18 series and foldable iPhone Ultra launch weeks away, TSMC's N2
process is producing A20 Pro wafers with strong yields and ample capacity, but a
severe mobile DRAM shortage is preventing completed wafers from being packaged,
creating inventory buildup and pressuring Apple and its supply-chain stocking.
Apple and its assemblers are urgently seeking additional mobile DRAM; Apple
currently relies mainly on Micron and also purchases from SK Hynix and Samsung.
TSMC's N2 is not the shipping bottleneck—A20 Pro production is effectively
ready, Tim Culpan said.
