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.
