Teledyne e2v is pleased to announce the start of full production of its 16 GB DDR4-X1 Flight Model (FM), expanding its portfolio of high-density, radiation-tolerant memory solutions for space applications. The new device is designed to support the growing processing and data storage requirements of AI-enabled satellites, large constellations, broadband Internet-from-Space, Direct-to-Device services, and optical inter-satellite communications. By combining high memory density, radiation resilience, and a compact footprint, the component enables spacecraft to handle increasingly demanding onboard computing workloads.

Initial samples of the 16 GB DDR4-X1 Flight Models were delivered to customers in October 2025, allowing early system integration and evaluation. The device supports data rates up to 2400 MT/s, provides single-event latch-up immunity above 43 MeV·cm²/mg, and offers radiation tolerance up to 35 krad TID, enabling reliable operation in mission-critical space environments.
