Qimonda AG has signed a license to make use of the XDR memory interface, according to Rambus Inc.

Rambus said Qimonda would use XDR for memories implemented in 75-nanometer manufacturing process aimed at game consoles, digital televisions, set-top boxes and PC graphics.

XDR makes use of differential signaling and "Octal Data Rate", a technology that transfers eight bits of data on each clock cycle; four times as many as DDR (Double Data Rate) clocking.

A single 2-byte wide, 3.2-GHz XDR DRAM component provides 6.4 Gbytes per second of peak bandwidth, and enables PCB savings and cost savings by utilizing the fewest number of ICs, Rambus said.

"Since signing a patent license agreement with Qimonda, we have worked towards a relationship where our engineering teams could collaborate on leadership memory solutions to serve the global market," said Sharon Holt, senior vice president of sales, licensing and marketing at Rambus, in a statement. Robert Feurle, vice president and general manager of Graphics DRAM at Qimonda, said XDR completes Qimonda's graphics RAM portfolio, according to Rambus.
