BAE Systems Develops High-density, Radiation-hardened C-RAM Semiconductor

21 Jun 2006

MANASSAS, Virginia -- BAE Systems has introduced a radiation-hardened, 4Mb chalcogenide random-access memory, or C-RAMTM, semiconductor for space applications. The device is designed for system designers who need a high-density, radiation-hardened, non-volatile memory device and who previously relied on repackaged commercial devices or volatile memory with battery backup.

BAE Systems' C-RAM device provides the space community with a substantial improvement in density, write-cycle endurance, power consumption, and speed over other competing non-volatile technologies. The space industry as a whole is looking toward C-RAM as a replacement technology for commercial EEPROM and FLASH memories.

"The space market has been eagerly awaiting a true radiation hardened, high-density, non-volatile memory solution," said Laura Burcin, BAE Systems C-RAM program manager in Manassas, Virginia. "We expect C-RAM could become the de facto non-volatile memory solution in most future spacecraft missions."

BAE Systems has a 20-year history of providing radiation-hardened solutions for U.S. space programs. Its RAD6000 computers are installed on each of the Mars Exploration Rovers, launched in 2003. The only control and data computers aboard the two still-broadcasting Rovers, they continue to help execute that exploration. The RAD750 represents the next generation of space microprocessors and were vital in NASA’s Deep Impact mission.

Development of the new C-RAM technology was supported by funding from the Air Force Research Laboratory’s Space Vehicles Directorate.

More about the C-RAM

The 512Kx8 C-RAM is 3.3-volt product that offers 70ns read-cycle times, 500ns write-cycle times, low operating and standby power, and operates over the full military temperature range. C-RAM is total-dose-immune to 1 Mrad(Si), is latchup-immune, and has superior tolerance to single-event effects. The 4Mb devices are available in a 40-pin flatpack package. Deliveries of engineering models (P/N: 251A184) are scheduled to start in August 2006, and flight units in April 2007. The technology employs chalcogenide OUMTM technology, which is licensed from, and a trademark of, Ovonyx Inc.
