Teledyne e2v 8 GB DDR4 memory goes to space

12/06/2022

"Teledyne e2v today announced the availability of 8 GB of space-grade DDR4 memory as part of its Space Edge Computing solution. This announcement follows the successful conclusion of all internal de-risking activities including radiation/latch-up testing and initial industrialization checks Yes. With the surge in demand for small, high-density memory, Teledyne e2v emphasizes that its latest memory chips are compatible with all current high-end space processing components, including AMD/Xilinx VERSAL® ACAP processors, space-grade FPGAs, MPSOC, Microchip RT PolarFire® and numerous ASICs.

8 GB DDR4 engineering sample (EM) is now complete, flight feature film (FM) will be available in 2024


Teledyne e2v today announced the availability of 8 GB space-grade DDR4 memory as part of its space edge computing solution. This announcement follows the satisfactory conclusion of all internal de-risking activities including radiation/latch-up testing and initial industrialization inspections. As demand for small, high-density memory surges, Teledyne e2v emphasizes that its latest memory chips are compatible with all of today's high-end space processing components, including AMD/Xilinx VERSAL® ACAP processors, space-grade FPGAs, MPSOCs, Microchip RT PolarFire ® and numerous ASICs.




Ultra-fast, high-density 8GB space-grade DDR4 memory with the same form factor and pin compatibility as previous 4GB products, ideal for optimizing next-generation spaceborne development applications.


Modern satellite payloads store and convert vast amounts of data on a minute-by-hour basis; tasks such as Earth observation require tens of gigabytes of storage. Therefore, these tasks place greater emphasis on the bandwidth, access time, power consumption, physical size and storage capacity of existing memory products. Additionally, microsatellites and cubesats have specific size and power constraints, while OEMs seek ever higher memory bandwidth for real-time processing.


"Fast DDR4 memory is a critical resource for modern data-intensive satellite systems. Complementing 4 GB of space-grade DDR4, the new 8 GB version doubles the memory density in the same small and pin-compatible form factor. FM is expected to launch in 2024. In addition, with specific temperature grades and NASA Class 1 quality certification, Teledyne e2v offers the most rugged and versatile space-grade memory products.” Marketing and Business of Data Processing Products development manager Thomas Guillemain said.


The new 8 GB DDR4 memory has a single event lock-up (SEL) immunity of over 60 MeV.cm²/mg. Moreover, it has a target total ionizing dose (TID) of 100 krad and a SEU/SEE test of over 60 MeV.cm²/mg. From the outside, the 8 GB version is the same size as the previous 4 GB version (i.e. 15mm x 20mm x 1.92mm), i.e. doubling the storage density but still maintaining pin compatibility. In addition, the memory supports a transfer rate of 2400 MT/s.


What is de-risking?


De-risking refers to in-house engineering testing of new silicon products to verify their suitability for robust operation in the space environment. In addition, aerospace-grade components must pass a series of performance tests to extend the operating range of the target product.


Device Available (8 GB Version)


The first engineering samples will be released in the fourth quarter of 2022, while the final flight features are planned for the first half of 2024.
