Silicon Image, Inc. (SIMG) announced today that it is committed to creating an open standard for next-generation memory interface technology targeting mobile devices. The Sunnyvale, Calif.-based provider of semiconductor intellectual property solutions is part of an open-standard group that includes Sony Ericsson Mobile Communications AB, Hynix Semiconductor, Inc., LG Electronics, and ARM.

The companies are collaborating to create a standard for dynamic random access memory (DRAM), named Serial Port Memory Technology (SPMT(TM)), which will enable extended battery life, bandwidth flexibility, significantly reduced pin count, lower power demand and multiple ports by using a serial interface instead of the parallel interface commonly used in today’s memory devices. The technology is expected to dramatically extend battery life while allowing high-performance media-rich applications, according to the companies.

“As DRAM content continues to grow for the new generation of mobile devices, it is becoming increasingly difficult for current technologies to keep up with the demand for longer battery life, greater bandwidth and design flexibility while reducing overall system cost,” said Jim Venable, head of Silicon Image’s Advanced Memory Technology Products. “Serial Port Memory Technology will be a game-changer in the way mobile device developers design new products that deliver significantly better battery life and a higher- quality user experience.”

Shares of Silicon Image were up 6% to $5.85 during late trading Tuesday.
