Removing the Threat of Sulfuration to DRAM Modules

Innodisk are now providing all DDR4 DRAM Modules with Anti-Sulfuration protection

Embedded operators are facing increasing difficulty with high sulfur content in their surroundings.  This can be attributed to the trends of IoT and edge computing where devices are moving out into  the field where environmental risks are greater.

Sulfur contamination will cause corrosion damage to DRAM modules and other sensitive equipment.  DRAM resistors use silver due to its high conductivity and stability. It is, however, susceptible to  corrosion from sulfide, especially in the form of hydrogen sulfide gas. Once the silver corrodes, it loses all conductivity. This will eventually lead to module failure and consequently the whole system crashing. Hydrogen sulfide gas exists in minuscule amounts in the atmosphere, but elevated levels are found in  areas with volcanic activity and areas with pollution from fossil fuels.   Other than the more obvious scenarios where one can encounter sulfur contamination, it is also seen  as a hidden danger in data centres. Data centre air intakes can carry contaminants into the building,  and urban areas will have higher hydrogen sulfide levels due to traffic and other forms of pollution.

Protecting DRAM modules and other sensitive components is essential as the number of devices  around us grows and the risk of sulfur contamination increases. Sulfur can be an unaccounted  risk factor in many embedded environments and can cause significant damage if ignored.
