Rambus (NASDAQ: RMBS)
Rambus (NASDAQ: RMBS) is a leading chip and silicon IP provider delivering high-performance, high-security solutions for data centers and AI infrastructure. Having shifted from patent licensing disputes, it now plays a vital role in memory interface and connectivity technologies.
Business Model and Revenue Streams 📦
Rambus runs a hybrid model combining high-growth product sales with recurring, high-margin licensing revenue—balancing stability with exposure to long-term tech trends.
- Product Revenue (Growth Driver): Derived from memory interface chips such as DDR5 Registering Clock Drivers (RCDs) and other components supporting next-gen data centers and AI workloads.
- Royalties (Stable Core): Long-term, high-margin income from licensing its extensive IP portfolio in memory and bus technologies.
