If this assumption proves to be incorrect, either or both of the parties understand that they may move pursuant to Rule 60 of the Federal Rules of Civil Procedure for relief from any

Access to and use of such documents shall otherwise be prohibited except as permitted in the protective orders in the DRAM consumer class actions or as permitted in the protective order the trial judge has indicated will shortly be entered in California Anti-trust Litigation.

8. Mutual Warranties. Rambus and Siemens each represents and warrants that it has not assigned, encumbered or in any manner transferred, in whole or in part, any claims it may have against the other or any other Releasee hereunder which otherwise would be a released claim under this Agreement.

EXHIBIT 12.13

Infineon Technologies and Rambus Conclude Broad Licensing Agreement

Agreement also settles all existing claims between the two companies

Munich, Germany and Los Altos, California: March 21, 2005 6 AM California – Infineon (NYSE and FSE: IFX)

and Rambus (NASDAQ: RMBS) announced that they have reached an

agreement settling all claims between them and licensing the Rambus patent portfolio for use in

current and future Infineon products.

Rambus has granted to Infineon a worldwide license to existing and future Rambus patents and

patent applications for use in Infineon memory products. In exchange, Infineon will pay a

quarterly license fee of US $5.85 million starting by November 15, 2005 through November 15, 2007. After November 15,

2007, and only if Rambus enters into additional specified licensing

agreements with certain other DRAM manufacturers, Infineon will make additional quarterly

payments which may accumulate up to a maximum of an additional $100 million.

The agreement also provides Infineon an option for acquiring certain other licenses. All licenses

provide for Infineon to be treated as a “most-favored customer” of Rambus.

Infineon has simultaneously granted to Rambus a fully-paid perpetual license for memory

interfaces.

In addition to the licenses, the two companies have agreed to the immediate dismissal of all

pending litigation and have released each other from all existing legal claims.
