Toshiba can't meet demand for flash memory and will only be able to provide 70 per cent of its existing order demands, according to the company's boss, Shozo Saito.

The company is being forced to turn excess orders away, as prices seem set to fall. "Demand is very strong," Saito said.

The Toshiba CEO confirmed the company to be planning to upgrade its flash memory manufacturing facilities to serve the demand, which is being driven by sales of digital media players and USB drives.

Worldwide flash memory growth is expected to reach 162 per cent in 2007, compared to 200 per cent last year, he said.
