To all our customers

Regarding the change of names mentioned in the document, such as

Hitachi Electric and Hitachi XX, to Renesas Technology Corp.

The semiconductor operations of Mitsubishi Electric and Hitachi 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 Hitachi, Hitachi, Ltd., Hitachi Semiconductors,

and other Hitachi 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.
