Engineering models of 16GB Space-qualified DDR4 memory released

Teledyne e2v has announced the immediate availability of Engineering Models for its new 16GB radiation-tolerant DDR4 memory. This high-density addition extends its space-grade DDR4 portfolio – already the most deployed in the industry – with hundreds of 4GB and 8GB flight models delivered to date.

The 16GB DDR4 device maintains the compact form factor of the existing family of just 15mm x 20mm x 1.92mm and is pin-to-pin compatible with the 4GB and 8GB variants. This compatibility provides a smooth upgrade path and enables system designers to scale memory capacity without a complete board redesign.

Fully compatible with all major space-grade processors and FPGAs, including the company's own LS1046-Space, LX2160-Space, and QLS1046-Space, the memory operates at speeds up to 2400MT/s. It is engineered for robustness in harsh space environments, with a TID tolerance of 100krad (Si), SEL immunity above 60MeV.cm²/mg, and advanced SEU/SEFI mitigation for reliable, no-data-loss recovery.

"As satellite payloads grow increasingly complex, the demand for higher memory densities becomes critical," said Thomas Guillemain, marketing and business development, Digital Processing Solutions at Teledyne e2v. "With the release of our 16GB DDR4 engineering models, system architects can begin early validation with confidence, preparing for a seamless transition to flight-qualified versions."

Engineering models of the 16GB DDR4 are available now, allowing early-stage development and system validation ahead of full flight deployment. The company supports the integration process with extensive documentation, including the latest 16GB DDR4 radiation report with its customers.

The company will also showcase the 16GB DDR4 Engineering Models at the 39th Annual Small Satellite Conference, held August 10-13, 2025, in Salt Lake City, Utah. Visitors can meet the team at Booth #23.
