Tap title to read story
South Korean prosecutors have launched a criminal probe into alleged international price-fixing in the semiconductor sector, raiding the local offices of three major chip suppliers. On Wednesday, 15 July 2026, the Fair Trade Investigation Division of the Seoul Central District Prosecutors' Office searched the South Korean offices of China’s Montage Technology, Japan’s Renesas Electronics, and U.S.-based Rambus Inc. Investigators suspect the firms colluded to manipulate prices of memory interface chips supplied to Samsung Electronics, SK Hynix, and Micron Technology. The chips, including Registering Clock Drivers and Data Buffers, are critical for high-bandwidth memory connections in advanced AI servers, a market dominated by the three companies.
