SST And Freescale Semiconductor Sign Embedded Flash Licensing Agreement

Freescale to Use SST's 180nm Embedded SuperFlash Technology for its Microcontroller Products SUNNYVALE, Calif., Feb. 13, 2006

— SST (Silicon Storage Technology, Inc., NASDAQ:  SSTI), a leader in flash memory technology, today announced it has expanded its licensing agreement with Freescale Semiconductor to include SST’s 180nm embedded SuperFlash technology.  The agreement underscores the success of SST’s high-reliability, high-performance SuperFlash technology and helps Freescale customers seamlessly migrate to next generation flash-based microcontrollers.

“SST’s 180nm SuperFlash technology is helping us to migrate our 0.25um HCS12 family of microcontrollers to the next geometry 0.18um process,” said Mike McCourt, vice president and general manager of Freescale’s microcontroller business.  “This allows us to continue serving our customers’ needs for higher and higher performance with next generation HCS12 microcontrollers while maintaining compatibility with previous generations. SST’s SuperFlash technology provides us with a low-power, high-reliability embedded flash solution that is helping us strengthen our position as the number one 16-bit architecture in the automotive market.”

“We are pleased to be able to continue our relationship with Freescale by providing it with advanced generations of our embedded flash technology,” said Bing Yeh, president and CEO of SST.  “Today’s agreement underscores SST’s SuperFlash as a leading embedded flash technology available today for the microcontroller market.”

Over the course of their partnership, Freescale has been a licensee of SST’s 0.50um and 0.25um before migrating to 0.18um SuperFlash technology.  The split-gate cell design and thick-oxide tunneling injection provide high reliability and robust manufacturability, and Freescale is using the SuperFlash technology to create products that are a key part of its portfolio of flash-based embedded microcontrollers.
