Tech Innovations & Market Shifts
DRAM market tightness ripples through Apple, smartphones and memory makers
Apple faces the imminent expiry of its long‑term DRAM agreements, which could force the Cupertino giant to pay premium prices to Samsung and SK Hynix starting January 2026, according to Wccftech. A concurrent analysis from the same outlet warns that SK Hynix projects commodity DRAM supply will lag demand through 2028, tightening the market further. The shortage is already prompting a shift in mobile design, with manufacturers considering a rollback to 4 GB RAM devices for entry‑level phones, as reported by Wccftech.
