• Memory Interface Chips: Rambus provides complete chipset solutions for industry-standard DDR5 and LPDDR5 memory modules for server and client systems. Key products include Registered Dual Inline Memory Modules (RDIMM) and next-generation Multiplexed Rank Dual Inline Memory Modules (MRDIMM). These solutions enable high memory subsystem performance, capacity, reliability, and power efficiency. The company sells these chips directly and indirectly to memory module manufacturers, OEMs, and hyperscalers worldwide through multiple channels, including its direct sales force and distributors. Rambus operates a fabless business model, using third-party foundries and manufacturing contractors to fabricate, assemble, and test its memory interface chips. This approach allows the company to focus on research, development, design, sale, and marketing of its products while reducing capital requirements.

• Silicon IP: Rambus Silicon IP includes high-performance interface and security IP solutions that move and protect data in advanced AI, data center, government, and automotive applications. The interface IP solutions feature high-speed memory and chip-to-chip digital controller IP, including HBM Memory Controller IP, GDDR Memory Controller IP, PCIe Controllers, Retimer and Switch IP, and CXL Controller IP. The security IP offerings comprise one of the industry's most comprehensive portfolios, including Hardware Roots of Trust, High-speed Protocol Engines, Crypto Cores, and Chip Provisioning Technologies. These solutions are sold to leading chip makers worldwide for integration into their custom silicon, Application Specific Standard Products (ASSP), and Field Programmable Gate Array (FPGA) designs. Rambus Silicon IP is sold primarily through its direct global sales force.

• Patent Licenses: Rambus's patented inventions are foundational to the semiconductor industry and are licensed to leading semiconductor and system companies around the world. The company's broad worldwide portfolio of patents covers memory architecture, high-speed serial links, and security. These licenses enable customers to use specified portions of Rambus's patented inventions in their own digital electronics products, systems, or services. License agreements are structured with fixed or variable, or a hybrid of fixed and variable royalty payments over certain periods, typically ranging up to ten years. Leading semiconductor and electronic system companies, such as AMD, Amlogic, Broadcom, CXMT, IBM, Infineon, Kioxia, Marvell, MediaTek, Micron, Nanya, Nuvoton, NVIDIA, Phison, Qualcomm, Samsung, Silicon Motion, SK hynix, Socionext, STMicroelectronics, Toshiba, Western Digital, and Winbond, have licensed Rambus's patents.
