The announcement of the "major smartphone manufacturer" came
in late September of last year:

<<September 30, 2011
Cryptography Research Signs License With Major Smartphone Manufacturer

Agreement covers Differential Power Analysis countermeasures

SAN FRANCISCO--(BUSINESS WIRE)-- Cryptography Research, Inc. (CRI), a division of Rambus Inc. (NASDAQ:RMBS), today announced it has signed a license agreement with a major smartphone and tablet manufacturer for the use of CRI's Differential Power Analysis (DPA) countermeasures patents. Under the agreement, ongoing royalties will be paid for the use of CRI's patented innovations. Specific terms of the agreement and disclosure of the manufacturer are confidential.>>

As we can see the Canadian revenues spiked in late 2011:

<<In North America, the United States and Canada each represented more than 10% of the Company’s total consolidated revenue for the three
months ended September 30, 2011. In North America, no single country other than the United States represented more than 10% of the
Company’s total consolidated revenue for the nine months ended September 30, 2011 and the three months ended September 30, 2010. In North
America, no single country represented more than 10% of the Company’s total consolidated revenue for the nine months ended September 30,
2010. >>

As we can see on page 19 here (of the document), the Canadian revenue
appears to be recurring to the tune of about $1.9 million per quarter:

So, the bottom line is that Rambus' CRI division apparently received
a pretty healthy up front payment from the "major smartphone manufacturer"
(which I believe is RIM) as well as decent quarterly royalty payments.

It looks like the up front payment was in the $12 million range.

If Rambus can sign some new deals, I'd say they're in pretty good shape
with regard to contributions from their CRI division.
