What: Shares of Rambus (NAS: RMBS) are ringing in the new year with some upside, up by as much as 11% today after the company updated its fourth-quarter guidance.

So what: For the quarter that ended Dec. 31, it sees revenue guidance of approximately $83 million, topping previously provided guidance of between $66 million and $71 million.

Now what: The press release is devoid of any details beyond that, and didn't attribute the strength to any particular reasons. The Street consensus called for $69 million, so Rambus has left that estimate in the dust.
