Business Description

Overview Rambus is a global semiconductor company providing industry-leading chips and silicon IP for data-intensive computing systems, focusing on data center and artificial intelligence (“AI”) infrastructure. As a pioneer with over three decades of advanced semiconductor design experience, Rambus is at the forefront of enabling the next era of AI-driven computing, addressing the critical challenges of signal and power integrity at increasingly extreme data rates in the data center, edge and client markets. We are a leader in high-performance memory subsystems, offering a balanced and diverse portfolio of products, IP and patents that maximize performance and security in computationally intensive systems. The ongoing proliferation of AI is placing unprecedented demands on computing infrastructure, requiring massive amounts of processor performance and extremely high memory bandwidth. As workloads grow in size and diversity, system performance becomes memory bound, making the memory interface technology a critical determinant of overall throughput. This persistent gap between processor performance and memory subsystem capabilities remains one of the largest bottlenecks in high performance compute systems. In addition, power management is increasingly important to optimize system efficiency and thermal performance as the power-performance demands continue to rise. Rambus is well positioned to address these challenges. Leveraging our deep expertise in memory technology and innovative architectures, we provide industry-leading memory interface chips that enable the highest bandwidth, capacity and power efficient server memory modules, maximizing memory performance and reliability for the most demanding data-intensive workloads. Beyond the data center, server-class technologies are migrating into client devices to bring these same benefits to end-user systems, such as AI personal computers (“PCs”). Furthermore, the growing adoption of AI and heterogenous computing across diverse applications is creating significant opportunities for our silicon IP portfolio. Our high-performance digital controller cores are increasingly vital components in accelerated computing chips, including custom silicon, which are the workhorses of AI processing. The expanding attack surface in today’s accelerated computing environments also necessitates robust security solutions. Our industry-leading security IP plays a crucial role in safeguarding both data at rest and data in motion, protecting against evolving cyber threats. Rambus is committed to the sustained investment in our technology development and product roadmap to stay at the forefront of the innovation cycle and advance our product leadership. In 2025, Rambus delivered strong execution across our memory and interface portfolio. We strengthened our leadership in DDR5 Registering Clock Drivers (“RCD”) and expanded the adoption of our new products, contributing to revenue growth. We expanded into high-performance and AI PCs with the launch of our complete client chipset, giving Rambus a comprehensive portfolio that supports all JEDEC-standard DDR5 and LPDDR5 modules across server and client systems. We also achieved strong customer momentum across our HBM4, GDDR7 and PCIe 7.0 digital IP families, along with our security IP, reinforcing our position as a key enabler of next-generation data center and AI architectures. Finally, further fueling our continuous technology investment, we successfully secured and extended key patent licensing agreements, providing a strong foundation for sustained cash generation and consistent return of value to our stockholders.…
