As the world's largest NAND chip suppliers, samsung himself alone occupy 37% of the world, and is twice the second Toshiba, capacity, technology is ahead of other companies.Now to catch up with other companies the possibility of samsung flash smaller, because two years ago for $14.4 billion a construction basic pyongtaek factory finished, samsung as the world's largest semiconductor factories, is expected to formally put into production in July, the main production 64 layer stack of a new generation of 3 d NAND flash memory.

In 2015, samsung announced the 15.6 trillion won ($14.4 billion) of semiconductor investment plans, will be in pyeongtaek, building the world's largest NAND fabs, is expected to be completed in the first half of 2017.Pyongtaek plant will play a key role in the business of samsung NAND, the future will be and samsung in gyeonggi province giheung city system DRAM memory semiconductor factories, China city factory form a triangle.

　　Pyongtaek factory is expected to formally put into production in July, although claims to be the world's largest semiconductor factories, production capacity is also a process, however, this year capacity may only 7-80000 wafer/month, after a year or two to run at full speed.Samsung plane and 3 d flash factory combined monthly production capacity is about 450000 wafers, pyongtaek factory will with 10-20% of the share.

　　Since be painstakingly construction of a new generation of factory, pyongtaek factory produces the product nature also is the latest 3 d NAND flash memory, samsung has released the stack layer are respectively before 24, 32, 48 layers of three generations of the 3 d NAND, pyongtaek factory production is expected the second half of the stack layer 64 the fourth generation of 3 d NAND flash memory.

　　According to data released before the samsung 64 layer stack of 3 d NAND core capacity up to 512 gb, IO interface speed is 800 megabits per second.

　　Before pyongtaek factory, samsung opened the $7 billion in xian NAND factories in China, the main products is current 3 d NAND 48 layer stack, the future of xi 'an factory will put into production 64 layer 3 d NAND flash memory.

    Samsung pyongtaek factory two or three years may have been the largest semiconductor factory in the future, but the biggest factory of title is likely to be replaced by the Yangtze river storage technology of China, the company in wuhan, bigger fabs, for the construction of nanjing in 2020 each fabs capacity up to 300000 wafers (12 inches), really want to put into production the two factory production capacity is enough to match all samsung NAND plant capacity, and wuhan base planning capacity is eventually reached 1 million wafers per month in 2030.

　　Violet light of high-level yesterday also said never compete on price, but the future of China's own production 3 d NAND flash memory available to the public, how could such a large capacity under no price war, not past good ways, domestic manufacturers into action is also likely to drive the 3 d NAND rises in price considerably from regression rational.
