Combination of leading suppliers accelerates position in SerDes IP and product offerings

SUNNYVALE, Calif. — (BUSINESS WIRE) — June 6, 2016 — Rambus Inc. (NASDAQ: RMBS) today announced it has entered into a definitive agreement to acquire the assets of Semtech’s Snowbush IP for $32.5 million as well as additional payments based upon specific new product sales through the end of 2022. Snowbush IP, formerly part of Semtech’s Systems Innovation Group, is a leading provider of silicon-proven, high-performance serial link solutions. The acquisition strengthens Rambus’ position in high-growth spaces and meets customer needs in the server, networking and data center market.

“Our strategy is to look for opportunities in critical segments that will enhance our roadmap, especially in ways that will propel growth in profitable markets,” said Dr. Ron Black, president and chief executive officer at Rambus. “By adding Snowbush IP into our portfolio, we are bolstering our SerDes business and accelerating our product position. This acquisition, along with our memory IP cores and chip business, will further build upon the existing product opportunities and expand our foundry partnerships.”

Snowbush IP has a long history of providing advanced analog and mixed-signal IP for ASSP, ASIC, and SoCs. The platform architectures developed for advanced SerDes products, along with high-speed IP cores, offer cost savings opportunities and can expand the Rambus product offerings by integrating industry-leading IP cores, patents and other assets.

This acquisition remains subject to customary closing conditions and is expected to close during the third quarter of 2016. These acquired technologies will be part of the Rambus Memory and Interfaces Division and Rambus expects this acquisition to be accretive within 18-24 months.
