Toshiba Corp. has signed a multibillion dollar, three-year strategic alliance and master purchase agreement for computer components with Dell Computer Corp., Toshiba's U.S. unit said Monday.

Under the deal, Toshiba will support development and supply of various computer components to Dell on a global basis, including memory, liquid-crystal displays and storage products, Toshiba America Electronics Components Inc. said.

The deal is potentially worth $5 billion.

As the relationship develops, the two expect to add other products, such as batteries and color display tubes, to the initial deal and renew it every 12 months, Toshiba America said.
