Techeye said that Rambus is to start selling DDR4 DIMM chipsets under its own name.

The memory chips are aimed at enterprises and have the catchy name RB26. The chips are already being sampled to customers. Rambus said in a statement that the RB26 is a memory module chipset for data intensive applications including real time analytics.

The chips, which will trade under the R+ chipset family, will be for Registered DIMMs (RDIMMs) and Load Reduced DIMMs (LRDIMMs) for server usage, with Rambus producing both the Register Clock Driver (RCD) chip for RDIMM/LRDIMM, and the data buffer chips for LRDIMMs.

RDIMMs and LRDIMMs allow servers to expand the amount of memory they can address and to do so at higher speeds. By interfacing with an RDIMM's RCD to better organise address and command signals, a CPU memory controller can handle more DIMMs and more memory per DIMM than standard unbuffered memory.

LRDIMMs attach buffers to the data bus of each RAM chip on a DIMM – essentially changing DIMM bus operation to a type of serial mode.

Although Rambus is producing their own DIMM chipsets, they will not be producing their own DIMMs or DRAM.

Rather the company will be offering their chipsets for sale to the DIMM vendors such as Hynix, Micron, or Samsung to use in building their respective RDIMMs and LPDIMMs.

Ironically, these are the same companies which Rambus has caused legal headaches for in the past. Nvidia, Micron, Hynix and others have all been sued by Rambus and for some time its entire business model appeared to come from court actions.

The outfit is similar to ARM, only Arm does not like suing people as much.

It's not clear which foundry will manufacture the Rambus chips, but they're expected to be available later this year.

Rambus will show off its server memory chipset at this week's Intel Developer Forum.
