Overview
- Apple confirmed at WWDC 2026 that its most powerful on‑device Siri model requires 12GB of unified memory to enable more expressive voices and improved systemwide dictation.
- Reports on Tuesday say KB Securities (via DigiTimes and MacRumors) expects Apple to equip the standard iPhone 18 with 12GB of RAM to deliver the full Siri experience.
- KB Securities reports Apple has asked DRAM makers to increase LPDDR5X output and will buy mobile DRAM from Samsung, SK hynix, and Micron at premiums to guarantee supply.
- Sources say Apple plans to absorb the higher memory cost rather than raise device prices, a decision analysts warn could tighten DRAM availability for other smartphone makers.
- Analysts caution that higher per‑phone RAM needs and projected large iPhone volumes in 2027 could intensify near‑term DRAM pressure; Apple’s unified memory move reflects a shift toward more capable local AI models and away from cloud dependence.
