Japanese NAND Flash Toshiba (Toshiba) recently surprised the Japanese fabs emergency shutdown for weeks, affecting nearly 100000 pieces of NAND Flash capacity, industry fears that department for 3 d NAND technology conversion yield wreck, Japan provider, Toshiba is the cause of the accident shutdown fabs computer hackers malicious attacks by extortion software, lead to Toshiba decided to shut down for weeks to solve the problem, but also because of the unexpected shutdown event, it was originally to gradually into the fourth quarter of oversupply of NAND Flash market changes.
In 2017 when the NAND Flash industry radically different from the traditional 2 d to 3 d technology, the semiconductor factory in 64 and 72 layer 3 d NAND technology not very well, the process of deepening the industry a tight supply situation, the global supply of NAND Flash industry into the good times, prices, but the upstream industry make full, is bitter as the downstream industry.
