Rambus has announced that it will make the transition from licensing its IP to building and selling DDR4 memory modules aimed at the server market. Rambus has thus far earned loyalties on key patents it holds in this space, but is looking to diversify into the manufacturing segment.
The vendor will not be making the modules itself, it will join the likes of Qualcomm and Nvidia in becoming a fabless manufacturer, designing and chips and getting them built by a third-party fab. Rambus’ DDR4 DIMM chipsets will be marketed under the R+ family, with the first offering in the series being the RB26. Targeted at high capacity server systems, the RB26 is a JEDEC-compliant memory module that will be available in configurations ranging from 128GB to 256GB, with a frequency of 2666MHz to 2933MHz. The modules will be compatible with all microprocessors, including Intel’s Xeon series:
- JEDEC DDR4 Compliance: fully-compliant with the latest JEDEC DDR4 RCD and DB specifications at 2666 Mbps with built-in support for future data rates;
- Industry-leading Performance and Margin: advanced I/O programmability and power management techniques allow for broad compatibility and increased efficiency in critical server infrastructures; and
- Advanced Debug and Serviceability: integrated tools and added device flexibility provide a robust system while delivering ease-of-integration and enhanced testability for server OEMs.
By using Registered DIMMs and Load Reduced DIMMs, which increase memory densities and reduce the load on the processor by placing a buffer between the memory controller and the address lines of the processor, Rambus is targeting energy efficiency and high performance. These modules, which feature Rambus’ Register Clock Driver (RCD) and Data Buffer (DB), will be built by the likes of Hynix, Samsung, and Micron, along with the DRAM.
