Renesas Technology's superAND Flash Memory Driver Software Gains Symbian OS Compliance; Renesas Technology Joins Symbian Companion Technology Program.

LONDON & TOKYO -- Renesas Technology Corp. (NYSE:HIT)(TSE:6501)(TSE:6503) today announced that the driver software for Renesas Technology's superAND flash memory will be included with Symbian OS(TM) deliveries to Symbian OS licensees. Through the Symbian Companion Technology Program, Renesas Technology will provide handset manufacturers producing smartphones based on Symbian OS an easy and low risk mechanism to evaluate superAND flash memory to their phones. Symbian OS(TM) is licensed to the world's leading mobile phone manufacturers.

The Symbian Companion Technology Program is designed to stimulate and promote innovation by offering Symbian OS licensees, who include Fujitsu, Motorola, Nokia, Sharp and Sony Ericsson, a choice of a wide range of pre-integrated and pre-validated technologies to reduce handset time-to-market and commercial risk. The partners offering companion technologies license their software directly to handset manufacturers should the licensees decide to integrate it with their products.

Driver software usually requires significant investment of time and development resources by a mobile phone manufacturer in order to check its OS compatibility. In some circumstances it can delay the time-to-market of a product. Even though most semiconductor manufacturers now provide such driver software, it is still difficult to gain certified OS compliance, and in most cases driver implementations need further work before they are suitable for release in a product.

Renesas Technology's superAND flash memory is a leading device in the industry to built-in the error correction feature (Note 1), the wear leveling feature (Note 2) and the sector management function (Note 3), so generally the superAND flash memory reduces a system design load. Also, by the adoption of the AG-AND multi level cell technology (Note 4) it realizes high-speed programming and small chip size in same time.

Notes to Editors

(Note 1) The Error Correction Feature:

When an error is detected during READ operation, it is corrected by the memory chip itself.

(Note 2) The Wear Leveling Feature:

The wear levelling feature is a function to even out the number of rewrites. As a chip becomes susceptible to damage if write operations are concentrated locally, when rewrite operation reaches a predetermined number of times, data and addresses are automatically switched to an area in which few rewrites have been performed.

(Note 3) The Sector Management function:

This guarantees 100% error free sectors. The flash memory chip itself will detect and replace any bad sector automatically.

(Note 4) The AG-AND Technology:

The unique AG-AND (Assist Gate) memory cell structure adopts a field isolation method which combines assist gates and floating gates to prevent inter-cell interference. It realizes high speed programming (4MBytes/second at 512 Mb superAND flash memory) and a small chip size by using multi-level cell technology.
