On July 15, 2026, the Fair Trade Investigation Department of the Seoul Central District Prosecutors' Office conducted a surprise raid on the South Korean offices of China's Montage Technology, Japan's Renesas Electronics, and the US-based Rambus on suspicion of violating the Fair Trade Act, investigating their alleged collusion on memory interface chip prices. These three companies are major suppliers in the global memory interface chip market, with key clients including Samsung Electronics, SK Hynix, and Micron. During the raid, prosecutors seized mobile phones and corporate documents from relevant personnel at some companies to further investigate whether information exchange and collusion occurred, the specific timing and scope, as well as the impact of such actions on actual supply prices. Montage Technology responded by stating that the company is currently reviewing the situation, will actively cooperate with the investigation, and that its operations remain normal.
