"This is a strong endorsement of our latest generation chip technology," said Bob Eulau, senior vice-president and chief financial officer at Rambus.
Rambus has developed two technologies for memory and system bus interfaces. The memory interface, known as Yellowstone, allows data rates of 3.2GHz to 6.4GHz, which is much faster than conventional DDR (dual data rate) memory technology. It is ideal for high-performance memory applications, said Laura Stark, vice-president of Rambus' memory interface division.
Yellowstone was introduced in November with a licensing agreement between Toshiba and Rambus.
Rambus' latest processor bus, Redwood, is a high-speed parallel interface that delivers data to various integrated circuits on a processor. Redwood is a low-cost, low-power interconnect technology, Stark said.
Consumer electronics devices and broadband devices will be developed with the technology under a Sony-Toshiba-IBM project called Cell, which will work on a chip architecture for consumer devices to take advantage of high-speed Internet connections, Stark said. IBM will have access to Yellowstone and Redwood through that company's agreements with Sony and Toshiba, but IBM and Rambus have not signed a direct licensing agreement, she said.
Rambus technology was used in Sony's highly successful Playstation 2 gaming platform, and will likely be used in future products from the company, Sony said in a press release. Toshiba said it would use the technology in its DRAM (dynamic RAM) products.
Rambus would not comment on specific financial terms of the deal. The company will collect contract revenue of approximately $28m (£17m) from contract work with its partners over the next 18 months, and royalties from the eventual sale of products with the technology in a few years, Eulau said.
