To all our customers

Regarding the change of names mentioned in the document, such as Mitsubishi Electric and Mitsubishi XX, to Renesas Technology Corp.

The semiconductor operations of Hitachi and Mitsubishi Electric were transferred to Renesas

Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog

and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.)

Accordingly, although Mitsubishi Electric, Mitsubishi Electric Corporation, Mitsubishi

Semiconductors, and other Mitsubishi brand names are mentioned in the document, these names

have in fact all been changed to Renesas Technology Corp. Thank you for your understanding.

Except for our corporate trademark, logo and corporate statement, no changes whatsoever have been

made to the contents of the document, and these changes do not constitute any alteration to the

contents of the document itself.

Note : Mitsubishi Electric will continue the business operations of high frequency & optical devices

and power devices.
