Rambus, a memory and interface technologies designer, on Monday said that it had renewed its patent license agreement with Renesas Electronics. The companies did not specify which technologies the Japanese company obtained from Rambus, but it looks like there are a number of them.

“This license with a global leader of the semiconductor industry represents continued validation of the strength of our patent portfolio. We have enjoyed a long and positive relationship with Renesas Electronics, and we are pleased to renew this important agreement with one of the top five semiconductor companies," said Sharon Holt, senior vice president and general manager of the semiconductor business group at Rambus.

This agreement covers the use of Rambus patented innovations in a broad range of logic integrated circuit (IC) products offered by Renesas Electronics. Specific terms of the agreement are confidential.

Rambus recently launched another series of attacks onto open-standard interface technologies, such as DisplayPort, PCI Express, Serial ATA, Serial Attached SCSI. The company accused a number of semiconductor manufacturers, including Broadcom Corp., Freescale Semiconductor., LSI Corp., MediaTek, Nvidia Corp. and ST Microelectronics and demanded the U.S. trade commission to halt sales of their chips that infringe its patents as well as products powered by those chips. Apparently, the company wants to stop sales of almost all electronics available today, including personal computers, workstations, servers, routers, mobile phones and other handheld devices, set-top boxes, Blu-ray players, motherboards, plug-in cards, hard drives and modems.
