History of Changes
Data correction: Coverage of SK hynix's Q2 2026 earnings call says M15X's cleanroom opened in October 2025, wafer input began in the first quarter of 2026, and SK hynix expects to ramp volume gradually (and to accelerate the schedule further). The date shown is the end of Q1 2026; no exact day was given. The record previously showed Under Construction.
