Question · Q3 2025
Kevin Garrigan followed up on the MRDIMM opportunity, asking what more Rambus can do to capture market share or if it's primarily in the customer's hands. He also inquired about the traction with PCIe7 and secured IP within the silicon IP business.
Answer
Luc Seraphin (CEO) stated that MRDIMM share capture depends on customers, Rambus, and platform deployers (Intel/AMD). He emphasized Rambus's complete chipset for MRDIMM is critical for interoperability, especially with doubled capacity and bandwidth, and that Rambus's long-term investment in signal and power integrity, combined with a complete chipset, aids in development and testing. Regarding silicon IP, Luc Seraphin (CEO) broadly split the business: security accounts for about 50% (widespread applications, faster cycle) and controllers (memory/PCIe) for the other 50%. He noted PCIe and HBM involve working with fewer, larger customers on bleeding-edge solutions (HBM4, PCIe7) for data center/AI, characterized by higher ASPs and longer development cycles.
