Aeroflex offers radiation-tolerant solid-state memory chips

COLORADO SPRINGS, Colo., 3 Nov.. 2007 Aeroflex in Colorado Springs, Colo., is announcing the production of 4- and 16-megabit radiation-tolerant 5-volt static random-access memories (SRAMs) that are able to withstand 50 kilorads total-dose radiation for satellite applications.

The QCOTSTM (Quantified Commercial Off-the-Shelf) family of SRAMs are for satellite and communications payload systems integrators who need an assured memory solution for high-reliability environments, Aeroflex officials say.

These devices first were made available in 1999 to offer high-performance commercial off-the-shelf (COTS) products to the aerospace marketplace with quantified radiation performance. The QCOTS family is qualified as QML T and Q and has a proven flight record, company officials say.

"Aeroflex's continued testing of commercial die sources determined in 2005 that future die would be unacceptable for high reliability applications," says Anthony Jordan, director of standard products at Aeroflex.

The UT9Q512E 4M and the UT9Q513K32 16M 5-volt RadTolerant SRAMs are now available as a QML Q SRAM solution. Improvements to the products during the migration included improved radiation effects and less than half the power consumption over the legacy QCOTS products. The UT9Q512E and the UT9Q513K32 are available in 36- and 68-pin packages, but with slightly different dimensions.
