TOKYO (Reuters) - Two Japanese manufacturers of Western Digital company's Fells memory have admitted that some contaminants at a highly sensitive plant have affected memory production and damaged some memory chips.
According to international media reports, Western Union said in a statement that two of its production units in Japan have been affected by some form of pollution which has halted production.
The private company is called Kyoxia Holdings, which manufactures solid-state flash memory, or USB memory, for Western Union, the world's largest maker of flash memory.
According to the Japanese company, the production of at least 6.5 exabytes of flash storage has changed and many flash memories have deteriorated. Note that one exabyte is equivalent to one billion gigabytes of storage or memory.
This has led to a total loss of 7 billion gigabytes of memory.
Top Western Union officials have since contacted Japanese companies on an emergency basis and are working hard to resolve the issue.
It should be noted that in electronics, microchips, processors, and memory sticks are manufactured in a very clean environment. Their indoor factory is said to be 10 times cleaner and dust-free than the operating theater of a modern hospital.
That is why even a small particle of sand in their preparation can destroy the processor and memory.
