Toshiba and Sony have unveiled new chip-making technology for mobile devices.
The companies plan to have the technology ready for use by March 2004 to make narrower and faster microchips with circuitry of only 65 nanometers (just billionths of a metre).
The chips would be only a quarter of the size of current devices while offering higher levels of performance.
According to Reuters the three-year, ¥15bn ($77m) project shares the research and development bill to develop the ever-thinner circuitry.
This latest product is two steps ahead of the 130-nanometer technology that the world's leading chip makers have begun selling over the past year, and better than the 90-nanometer processes expected next year.
The new chip incorporates dynamic random-access memory (Dram), logic and other functions in a single chip.
