According to Japanese media reports, Toshiba's NADN flash memory factory had a power failure at 6:25 p.m. local time on June 15. The blackout was very short and power was restored 13 minutes later. However, the factory was shut down until the morning of 21. It was not restored until at least 5 days after the blackout. Officials explained that it usually took several days to several weeks for the accident to resume normal operation.

Semiconductor factories have their own particularities. They operate for 24 hours. Once an accident stops, it is not that they can resume production after the call. It is important to check the damage of the equipment and, more importantly, to ensure that the wafers on the survival line are affected. If the wafers are damaged, the quality of the chip will be affected. In serious cases, a large number of wafers will be scrapped. The wafers appeared at the beginning of the year in TSMC. The round pollution incident scrapped 100,000 tablets, equivalent to one month's production capacity of the plant, with a direct loss of up to $550 million.

Toshiba hasn't yet announced how much damage the blackout caused, maybe it's still in the statistics, but the NAND factory in the city of Four Days after the accident is very important. It started construction in 2017. It was put into operation last year. It was operated by Toshiba and Western Mathematics. It is the main factory of NAND flash memory of both sides, accounting for 40% of the world's production.
