Wuts RAMBUS? Lulz.
These sorts of get rich quick "companies" need to DIAF. It's like, I'll start a company, patent some universally common sense idea like "the wheel" with a vague patent that says "round thing", not make any legitimate contribution or product, then start suing everybody. Nope.
Rambus actually had, and still has, great ideas on how to make fast memory products. Innovation and value-add wasn't their issue.
Their issue was their business tactics, their corporate ethics, and their arrogance.
Had they not been so shady, essentially tricking the JEDEC into incorporating their proprietary IP into the DDR standards, and had they not been so arrogant, approaching the memory makers as if they were Intel Jr. just because Intel said Rambus was their favored memory standard going forward, then the memory makers themselves probably would not have solidified their resolve to make DDR and DDR2 work "no matter what the cost" to undercut and undermine Rambus ram.
More expensive products happen, and if they add value then their expense is accepted and absorbed (see SSD's). But the reality was that NO ONE wanted to see Rambus become the defacto standard because they were such bullies of the industry despite being so small.
The corporate ego and arrogance were their own undoing. No different than how people tend to limit their own personal career paths, so too did Rambus as a business.
No one wants to do business with a dick unless they have no choice. Rambus was the corporate equivalent of a dick.
