  NASA Certification: The World's First DDR4 Memory Born Without Cosmic Radiation
  Can fly into space, dramatic high and low temperature changes and cosmic radiation are not afraid of DDR4 memory to see? Teledyne e2v, a semiconductor company from France, brings the magic of the product, the DDR4T04G72M. The memory is available in a single-chip package with a size of only 20 x 15 x 1.92 mm, and is internally integrated with multiple Micron memory chips with a bit width of 72-bit, of which 64-bit is used to transmit data and 8-bit is used for ECC error checking.
  The chip was tested for radiation resistance at the factory, and the official single particle effect (SEE) test report was issued, with a maximum of 60 plus MeV.cm2/mg of single particle locking (SEL).
  It can also withstand severe high and low temperature changes of up to 125 Degrees C and minimum -55 degrees C, which are standard in accordance with NASA Level 1 (NASA EEE-INST-002 – Section M4 – PEMs), ECSS Class 1 (ECSS-Q-ST-60-13C).
  In terms of performance, a single capacity of 4GB, currently verified frequency of 2133MHz, will be upgraded to 2400MHz in the future.
