Default Toshiba & WD NAND Production Hit By Power Outage: 6 Exabytes Lost

Toshiba Memory and Western Digital on Friday disclosed that an unexpected power outage in the Yokkaichi province in Japan on June 15 affected the manufacturing facilities that are jointly operated. Right now, production facilities are partially halted and they are expected to resume operations only by mid-July.

Western Digital says that the 13-minute power outage impacted wafers that were processed, the facilities, and production equipment. The company indicates that the incident will reduce its NAND flash wafer supply in Q3 by approximately 6 EB (exabytes), which is believed to be about a half of the company’s quarterly supply of NAND. Toshiba does not disclose the impact the outage will have on its NAND wafer supply in the coming months, but confirms that the fabs are partially suspended at the moment. Keeping in mind that Toshiba generally uses more capacity of the fabs than WD, the impact on its supply could be significantly higher than 6 EB with some estimating that it could be as high as ~9 EB.

Both companies are assessing the damage at the moment, so the financial harm of the incident is unclear. Not even counting potential damage to production tools and other equipment used at the fabs, 6 EB of NAND cost a lot of money. Furthermore, analysts from TrendForce believe that a consequence of the outage will be some loss of confidence from clients of both companies, which will have a financial impact as well.

The Yokkaichi Operations campus jointly owned and run by Toshiba and Western Digital produces about 35% of the global NAND output in terms of revenue, according to TrendForce. At present, the manufacturing base has five production facilities (Fab 2, Fab 3, Fab 4, Fab 5, and Fab 6) as well as an R&D center, all of which were affected by the outage. Three fabs within the campus produce 3D NAND flash, whereas another two are used to make special-purpose types of memory.
