Rambus is an interesting company. I can't vouch for their crypto offerings, but they have been around since the 90's and at one point pioneered high-speed DRAM interfaces. Lots of what we see in DDR today is based on ideas and concepts they pushed forward in their proprietary interface. Early on, they definitely did innovative work.

IIRC, their interfaces were used in some Sony play-stations and also some Intel systems.

I think it was Nintendo who put Rambus DRAM in the N64

The N64 did use Rambus RDRAM, but the PS3 also used Rambus XDR memory.
