Teledyne e2v has announced the start of full-scale production of its 16GB DDR4-X1 Flight Model, marking a significant advancement in high-density, radiation-tolerant memory solutions for space systems. The new device is engineered to meet the growing data processing and storage requirements of next-generation satellites. It supports applications such as artificial intelligence-enabled payloads, large satellite constellations, broadband connectivity from space, direct-to-device communication, and optical inter-satellite links.
Initial samples were delivered to customers in October 2025, enabling early-stage system integration and evaluation. The memory supports data rates of up to 2400 MT/s and is designed to withstand harsh space environments, offering single-event latch-up immunity above 43 MeV·cm²/mg and radiation tolerance up to 35 krad total ionizing dose.
Maintaining a compact footprint of 15 × 20 × 1.92 mm, the device is pin-compatible with other DDR4 components in Teledyne e2v’s portfolio. This allows satellite manufacturers to upgrade memory capacity without redesigning hardware, reducing development time and cost.
According to Luca Lo Coco, Vice President of Marketing, the transition to production reflects the program’s steady progress and readiness for deployment across multiple space missions. Supporting documentation, radiation test data, and customer support systems are already in place.
The 16GB DDR4-X1 memory is also integrated into the company’s Qormino QLS1046 space computing module, which combines a radiation-tolerant processor with high-performance memory. This platform enables advanced onboard processing capabilities, including AI inference, sensor data fusion, and autonomous spacecraft operations.
Teledyne e2v continues to expand its DDR4 portfolio, which includes 8GB flight models and a NASA Level 1-qualified 16GB version designed for geostationary and long-duration missions, expected to be available in the third quarter of 2026. This growing product range provides satellite developers with flexible options for memory density and qualification levels, ensuring compatibility and long-term support across diverse mission requirements.
Teledyne e2v develops high-reliability semiconductor solutions for space, defense, healthcare, transportation, and industrial applications. Its offerings include radiation-tolerant memory, microprocessors, and data converters, supported by specialized manufacturing and testing services. As part of Teledyne Technologies, the company focuses on delivering customized technologies that enhance system performance in demanding environments.
