Teledyne e2v Semiconductors announced the successful initial qualification of its 16 GB Space DDR4 memory, marking a key milestone in the advancement of high-reliability memory solutions for space-grade applications.
This 16 GB DDR4 device is part of Teledyne e2v’s growing portfolio of radiation-tolerant memory products, which includes the 8 GB DDR4 variant qualified last year. Doubling the capacity while maintaining the same form factor and pin compatibility, the 16 GB version offers seamless integration into next-generation satellite systems without requiring hardware redesign.
The initial qualification confirms the long-term reliability and robustness of the 16 GB DDR4 product. It was validated through extensive testing across three statistically significant production lots, ensuring both process consistency and performance reproducibility, critical factors for mission assurance in space environments.
Conducted in accordance with the stringent JESD47 standard, the initial qualification campaign included a comprehensive suite of reliability assessments to simulate the harsh conditions encountered in orbit, verifying the product’s resilience to temperature fluctuations, mechanical stress and radiation exposure.
“This milestone is foundational,” said Thomas Guillemain, Marketing and Business Development manager at Teledyne e2v. “It demonstrates that our 16 GB DDR4 memory is not only reliable but also supported by a robust and repeatable assembly process. Following the successful qualification of Teledyne e2v’s 16 GB Space DDR4 memory, the company has now entered the Flight Model (FM) production phase. Our first FMs – Teledyne e2v X1, designed for New Space and LEO missions – will ship this October, while NASA 1 Flight Models are on track for Q3 2026. Customers can now place orders to secure delivery for upcoming missions.”
As the previous generation, this memory solution is designed to be compatible with a wide range of space-grade processing platforms. Engineered to support the demands of modern, data-intensive space missions, from Earth observation to edge computing in orbit, it delivers the performance and reliability required for the most critical applications.
Teledyne e2v Semiconductors will be showcasing its latest innovations, including the newly qualified 16 GB Space DDR4 memory, at the Seoul ADEX in Seoul, South Korea, from October 20-23, 2025. Meet the team at booth 7-I5 and discover how their high-reliability memory solutions are shaping the future of space-grade applications.
