It is reported from foreign media that Samsung Semiconductor's NAND flash memory factory in Pingze City, South Korea, suffered an unexpected power failure of up to 30 minutes on March 9. It is reported that the power failure of NAND production line for more than 20 minutes will lead to more than half of the input wafers being scrapped, that is, about 50000 to 60000 wafers are damaged. It is estimated that nearly 11% of Samsung's NAND production capacity will be affected in March, This will also account for 3.5% of the global NAND flash supply.

Although some media said that Samsung's sufficient reserve inventory could offset the number of wafers lost in this accident, the shipment of NAND flash memory products in March was affected irretrievably, which means that the prices of products related to flash memory particles, such as memory modules and SSD solid state disks, will "rise again" significantly. As the only manufacturers capable of producing NAND flash memory chips, Samsung Semiconductor has a significant impact on the industry, and any capacity problem will significantly affect the market prices of memory and solid state drives.
