Rambus has developed a comprehensive PCIe 5.0 and CXL interface solution for chips built using 7 nm process technologies. The interface is now available for licensing by SoC designers and will enable them to bring PCIe 5.0/CXL-supporting hardware to the market faster.

Rambus’ PCIe 5.0 solution includes a controller core originally developed by Northwest Logic (which was recently acquired by Rambus) and is backwards compatible with PCIe 2.0, PCIe 3.0 and PCIe 4.0, as well as a PHY that also supports CXL. The solution supports 32 GT/s per lane data transfer rate and is designed for advanced 7 nm FinFET process technologies. Besides the IP itself, Rambus will also offer design, integration, and support services to speed up the development process.

Rambus believes that its PCIe 5.0 solution will be used by developers of processors for AI, HPC, storage, and 400 GbE networking applications. Considering the fact that many of the upcoming accelerator chips will use the CXL interface, it is important that Rambus’ PHY also support the new technology.

Rambus did not disclose how much its PCIe 5.0 solution will cost to its licensees.

    Rambus is hardly the most evil company out there these days. Creepy-as-fuck Google's desire to data mine the fucking stuffing out of everything everyone does makes shitty old Rambus look like a candidate for sainthood. Reply

    It was the beginning of the end for them when they decided 'don't be evil' had to go to allow some of their more profitable ventures. Reply

    Eh, memory cartels and the various illegal agreements they do are about as shitty. So, their operation is about on par for the market :) Reply

    Eyebrow-raising that Rambus is deemed as excrement and **F___-able** when Chipzillah spends tens of billions of dollars buying IP and developing "open standards" (cough-cough) that we are forced to stomach ...

    Yeah I hope it is a hard pass from everyone on this. Starve them of the funds to keep doing shitty things and they eventually die off. Reply

    What is exactly this company inventing. I see it is buying companies and claiming the benefits. Reply
