Teledyne e2v Introduces First Radiation-Tolerant DDR4 Memory for Space Applications
Teledyne e2v has announced the DDR4T04G72M - the first radiation-tolerant DDR4 memory chip, featuring a total 4 GB capacity. Currently validated at 2133 MT/s, and targeting to offer 2400MT/s in the near future, this next-generation solution offers ultra-responsive low latency operation, while fitting into a highly compact form factor. Furthermore, high-reliability manufacturing and radiation-tolerant robustness makes it highly suitable for dealing with the rigors of space environments.
With 15 mm x 20 mm x 1.92 mm dimensions, this new space-grade device comprises an array of Micron based memory chips, integrated in a single package. It features a 72-bit bus, where 64 bits are dedicated to data and 8 bits to error correction code (ECC). Radiation tests have been performed on these memory chips and a single event effects (SEE) report is available from Teledyne e2v. In particular, the memory has been demonstrated to be single event latch-up (SEL) free up to 60+ MeV.cm²/mg.
