Memory Interface Chip Giants Investigated for Price Fixing in South Korea
South Korean authorities are investigating accusations of price-fixing involving the world's top three memory interface chip makers: Innoscience, Renesas Electronics, and Rambus. The companies' South Korean offices were searched as part of the probe.
South Korean prosecutors have launched an investigation into three global memory interface chip (MIC) manufacturers over alleged price collusion. Innoscience, Japan's Renesas Electronics, and the US-based Rambus are the dominant players in this market, collectively holding over 93% of the global share.
The investigation was initiated by prosecutors who reportedly found evidence suggesting that the companies may have pre-arranged pricing for their MIC supplies to major clients, including Samsung Electronics and SK Hynix. Memory interface chips are crucial components that connect CPUs and GPUs to DRAM, regulating data flow for enhanced speed and stability, and are used widely in servers and personal computers.
As part of the coercive investigation, prosecutors searched the South Korean offices of all three companies, seizing mobile phones and corporate documents. The Seoul Central District Prosecutors' Office intends to analyze the confiscated items to determine the specifics of any information exchange and price coordination between the firms, and the impact on actual supply prices.
The global MIC market is highly consolidated, with Innoscience holding approximately 36.8% of the market in 2024, followed by Renesas at 36% and Rambus at 20.5%. The market is poised for significant growth, driven by the demand for AI servers. If found guilty of price fixing, the companies could face penalties, and their major clients might seek compensation for potentially overpaid costs.
