Rambus, a leading designer of memory and interface technologies, and Spansion, a leading maker of flash memory, have signed an agreement for DDR engineering services and a memorandum of understanding for future development of MirrorBit flash memory solutions.

Initially, Rambus will provide Spansion with DDR engineering services in support of accelerating time-to-market for robust, high-volume Spansion products. Services include signal integrity simulations, system and package design, and precision in-system voltage and timing margining.

“Flash memory content in electronic devices continues to grow, enabling increasingly innovative and differentiated consumer electronics products. Our deep flash memory expertise coupled with Rambus’ signal integrity and memory interface experience will provide an enhanced opportunity to create the next generation of advanced MirrorBit flash memory solutions,” said Ali Pourkeramati, executive vice president, Applications and Platform Engineering, at Spansion.

Rambus and Spansion signed a patent license agreement in early 2007. With a primary focus on the integrated flash memory market, Spansion solutions are incorporated into electronic products from original equipment manufacturers (OEMs), including the world’s top ten handset, consumer electronics and automotive OEMs around the world.

Unfortunately, there is no information about the actual products that Rambus an Spansion plan to develop together, therefore, a little can be said about their market prospects. If the final technologies co-developed by Rambus and Spansion remain proprietary, their market share may be limited to a number of devices only.
