About RAMBUS INC

Rambus Inc. (NASDAQ: RMBS) is a U.S.-based technology company focused on semiconductor chips and silicon IP for data-center connectivity, AI infrastructure, memory subsystems and hardware security. Founded in 1990 and listed on the public market in 1997, Rambus has built its reputation as a long-standing innovator in memory interface architectures and interconnect technologies. Its corporate headquarters are in San Jose, California, United States, placing the company at the center of Silicon Valley’s semiconductor ecosystem. For investors, Rambus is best understood as a specialized growth-oriented semiconductor platform with a hybrid business model that combines product sales, IP licensing and technology royalties. The company’s business is organized around a few core lines. First, Rambus designs and sells memory interface chips and chipsets for servers and client devices, with a strong emphasis on DDR5 and LPDDR5/LPDDR5X-based architectures. Second, it provides interface IP that helps customers move data efficiently between processors, memory and other subsystems. Third, it offers security IP and related CryptoManager solutions designed to protect data at rest, in use and in motion. This mix gives Rambus exposure to several critical bottlenecks in modern computing: bandwidth, latency, power efficiency and trusted hardware security. In competitive terms, Rambus occupies a niche but strategically important position. It is not a broad-based chip manufacturer; rather, it is a specialist with deep expertise in memory signaling, controller architectures and cryptographic security. That specialization, combined with a sizable patent portfolio and decades of engineering know-how, creates meaningful barriers to entry. Rambus serves a global customer base and maintains a geographically diversified footprint across North America, Europe and Asia, which is consistent with the supply chains and design centers of the semiconductor industry. Its key products include DDR5 server DIMM chipsets, MRDIMM-related solutions, SOCAMM2 server chipsets for AI systems, DDR5 client chipsets for next-generation PCs, LPCAMM2 client chipsets, and a broad set of security IP offerings under the CryptoManager umbrella. These products are aligned with structural demand trends in AI data centers, high-performance computing, and power-efficient client computing. Recent developments reinforce this strategic direction. In 2025 and 2026, Rambus announced new AI-focused memory products, including SOCAMM2 and HBM4E controller IP, as well as new client-memory solutions for AI PCs. Recent financial updates also highlighted strong product-revenue momentum and solid cash generation. Overall, Rambus appears well positioned as a niche enabler of next-generation computing, with its shares traded on the Nasdaq market in the United States.
