INVESTIGATION

Munich, Germany - September 15, 2004 - Infineon Technologies AG (FSE/NYSE: IFX)
announced today that it has reached an agreement with the United States

and limited charge related to the violation of US antitrust laws in connection
with the pricing in its Dynamic Random Access Memory business between July 1,
1999 and June 15, 2002. Consequently, with regard to the DoJ's ongoing industry

already been in contact with these customers and has achieved or is in the
process of achieving settlements with all of these OEM customers.
