Fun facts about RAMBUS INC

Quirks, history, and lore behind RMBS — the kind of stuff that makes a stock memorable.

  • 1
    The Basics
    U.S. semiconductor IP company · small-cap · listed on Nasdaq · headquartered in California's Silicon Valley.
  • 2
    The Numbers
    Annual revenue in the range of $300–400 million — modest for tech — but its licensing-heavy model means margins that would make a software CEO blush.
  • 3
    The History
    Founded in 1990, it pioneered high-speed memory interface technology and spent much of its early life locked in ferocious patent battles with the world's biggest chipmakers.
  • 4
    The Secret
    It barely makes chips itself — its real product is intellectual property, collecting royalties every time someone else's memory runs faster because of its innovations.
  • 5
    The Lore
    Its long legal war with Micron and Hynix became a landmark case in chip-industry patent law, and the word "patent troll" got thrown around liberally — fairly or not.
  • 6
    The Giveaway
    Its name is literally baked into RDRAM — the controversial Rambus DRAM standard that Intel once bet the industry's future on.
