Exhibit 99.3

                SANDISK FILES ACTION FOR DECLARATORY JUDGMENT OF
                 NONINFRINGEMENT AND INVALIDITY AGAINST INFINEON
                                 TECHNOLOGIES AG

      SUNNYVALE, CA, JUNE 25, 2003 - SanDisk Corporation (NSDAQ: SNDK) announced
today that it has filed a complaint for declaratory relief in the United States
District Court for the Northern District of California against Infineon
Technologies AG. The complaint seeks a declaratory judgment that SanDisk does
not infringe United States Patent No. 5,726,601 (the "`601 patent") and that the
`601 patent is invalid. SanDisk believes that its products do not infringe the
`601 patent, as alleged in a letter received from Infineon. The Company believes
Infineon's correspondence was motivated by Infineon's announced intention to
become a flash supplier. Infineon is not a SanDisk patent licensee.

      SanDisk Corporation, the world's largest supplier of flash memory data
storage card products, designs, manufactures and markets industry-standard,
solid-state data, digital imaging and audio storage products using its patented,
high density flash memory and controller technology. SanDisk is based in
Sunnyvale, CA.
