Teledyne e2v has announced the launch of 8 GB of spacegrade DDR4 memory as part of its Edge of Space computing solution. This announcement follows the successful conclusion of all internal de-risking activities, including radiation/latch effect testing and preliminary industrial inspection. As demand for small, high-density memory surges, Teledyne e2v stresses that its latest memory chips are compatible with all of today's high-end space-processing components, These include AMD/Xilinx VERSAL® ACAP processors, space-grade FPGas, MPSOC, Microchip RT PolarFire®, and numerous ASics

     Teledyne e2v has announced the launch of 8 GB of spacegrade DDR4 memory as part of its Edge of Space computing solution. This announcement follows the successful conclusion of all internal de-risking activities, including radiation/latch effect testing and preliminary industrial inspection. As demand for small, high-density memory surges, Teledyne e2v stresses that its latest memory chips are compatible with all of today's high-end space-processing components, These include AMD/Xilinx VERSAL® ACAP processors, space-grade FPGas, MPSOC, Microchip RT PolarFire®, and numerous ASics.The ultra-fast, high-density 8GB spacegrade DDR4 memory, with the same dimensions and pin compatibility as previous 4GB products, is ideal for optimizing the next generation of spaceborne development applications.

     Modern satellite payloads store and convert large amounts of data by the minute and hour; Tasks such as Earth observation require tens of gigabytes of storage. As a result, these tasks place greater emphasis on the bandwidth, access time, power consumption, physical size, and storage capacity of existing storage products. In addition, microsatellites and Cubesats have specific size and power limitations, while Oems seek higher and higher real-time processing memory bandwidth.

     "Fast DDR4 memory is a key resource for modern data-intensive satellite systems. Complementing the 4 GB space-grade DDR4, the new 8 GB version doubles the storage density in the same compact and pin-compatible form factor, and its FM is expected to launch in 2024. In addition, with specific temperature ratings and NASA Class 1 quality certification, the Teledyne e2v provides the most robust and versatile aerospace grade memory product available." "Said Thomas Guillemain, marketing and business development manager for data processing Products.

     The new 8 GB DDR4 memory has single particle locking (SEL) immunity of over 60 MeV.cm²/mg. Furthermore, its target total ionization dose (TID) is 100 krad, with SEU/SEE testing exceeding 60 MeV.cm²/mg. From the looks of it, the 8 GB version is the same size as the previous 4 GB version (i.e. 15mm x 20mm x 1.92mm), which doubles the storage density but still maintains pin compatibility. In addition, the memory supports a transfer rate of 2400 MT/s.
