Rambus to acquire Northwest Logic, expands offerings for data center, AI, ML, communications and automotive applications

Rambus Inc. announced that it has signed a definitive agreement to acquire Northwest Logic, vendor of memory, PCIe and MIPI digital controllers. Northwest Logic’s high-performance, high-quality and silicon-proven digital IP controller cores are optimized for use in both ASICs and FPGAs. 

Interface IP solutions consisting of a physical interface (PHY) and companion digital controller make it possible to optimize the transfer of data between chips and electronic devices. 

Every SoC design that uses a Memory or a PCIe or a MIPI PHY also needs to use a controller associated with it. The combination of complementary digital and physical IP portfolios from Northwest Logic and Rambus will create a one-stop-shop for customers.

Critical to enabling the high performance of data center, networking, AI, ML and automotive applications, this acquisition will bring together the physical and digital IP core families from renowned market leaders to offer comprehensive memory and SerDes IP solutions for chip designers.

The transaction is expected to close in the current calendar quarter of 2019. Although this transaction will not materially impact 2019 results due to the expected timing of close and acquisition accounting, Rambus expects this acquisition to be accretive in 2020.

“With this acquisition, we expand our leading product portfolio for high-performance markets such as data center, networking, artificial intelligence, machine learning and automotive,” said Hemant Dhulla, vice president and general manager of IP Cores at Rambus. “Northwest Logic’s innovative, best-in-class digital controllers complement Rambus’ proven strength in high-speed physical IP cores. Together, we will offer one of the most comprehensive high-performance interface IP solutions in the industry, leveraging our core strength in semiconductors, strong go-to-market advantage and global reach.”

“Northwest Logic’s category-leading digital controllers fit perfectly with Rambus’ leadership portfolio of high-speed PHY solutions,” said Brian Daellenbach, president and CEO, Northwest Logic. “This deal creates a one-stop-shop for SoC designers working on state-of-the-art applications across a broad range of high-performance markets. We look forward to continue serving our existing customers and working with our PHY partners.”

In 2017, Rambus announced validated interoperability between its HBM2 PHY and Northwest Logics’ HBM2 Memory Controller Core. The solution builds on the growing ecosystem of Rambus partner products that interoperate with its latest HBM2 PHY IP core. The combined HBM2 solution is designed to support high-performance networking and server applications in the data center and communications markets that require the maximum amount of bandwidth available through HBM2.

The Northwest Logic HBM2 Memory Controller Cores are optimized for use in both ASICs and FPGAs, and support full-rate, half-rate and quarter-rate operations. The cores provide a solution that can be configured to exact customer requirements, are silicon-proven and are verified with the Rambus HBM2 PHY.

The Rambus HBM2 PHY and Northwest Logic HBM2 Memory Controller are each fully JEDEC compliant to the HBM2 standard, allowing the PHY and memory controller to interoperate.

The Rambus HBM2 PHY is a high-performance memory IP core that features reduced power consumption and a small form factor. It combines 2.5D packaging with a wider interface at a lower clock speed, delivering higher efficiency and lower power consumption compared to other memory solutions on the market.
