My fellow comments aren't actually getting to the point: The original release of the Pentium 4 used Rambus RAM, instead of the JEDEC standard of the time.

This Pentium 4 was released in the year 2000.

So, yes, Rambus, the company, is a known quantity. Just weird they're into crypto now, because trying to wiggle into this already crowded patent landmine is certainty an... interesting choice.

They bought Paul Kocher's Cryptography Research in 2021. Cryptography Research designed the Blu-Ray BD+ licensing system and owned a huge IP portfolio on differential power analysis, a technique Kocher, one of the godfathers of side channel cryptanalysis, invented. They also ran (run?) one of the industry's best cryptographic consultancies. If you're a major hardware vendor going to market with a new cryptographic coprocessor, you're very likely going to engage Rambus.
