Qimonda AG has entered a long-term cross license agreement with Ovonyx Inc. for discrete memory products using Ovonyx’s and Qimonda’s patents and intellectual property relating to Phase Change Random Access Memory (PCRAM) technology.

The agreement also provides that Ovonyx will actively support Qimonda’s program to develop phase change memory products.

Ovonyx PCRAM technology uses a reversible phase-change memory process that provides for high performance, dense, array-addressed semiconductor memory technology that can be used as flash and DRAM memory replacements, as well as in embedded applications such as microcontrollers and reconfigurable MOS logic.

Qimonda, formerly the memory division of Infineon Technologies, has experience and a significant portfolio of intellectual property relating to phase change memories through its research and development in the general field, including its present joint research program with IBM and Macronix. Indeed, the trio in December demonstrated a prototype phase-change memory device that switched more than 500 times faster than flash while using less than one-half the power to write data into a cell.

“Ovonyx’ PCRAM technology has the potential to revolutionize the flash and DRAM businesses,” said Kin Wah Loh, president and CEO of Qimonda, in a statement. “With the support of Ovonyx we will expand our program to exploit this emerging technology and be well prepared for its commercialization.”
