Split-second power outage knocks Toshiba memory factory offline

How much disruption could a 0.07 second power outage really cause? If you're running Toshiba's NAND flash production facilities, apparently the answer is quite a lot.

According to the Wall Street Journal, the world's second largest manufacturer of flash memory suffered a momentary voltage drop at one of its plants in Japan early on Wednesday that caused it to shut down until today. The critical power loss forced many systems offline and though the damage is still being assessed, Toshiba believes that it could reduce shipments for the next two months by as much as 20 per cent.

Since the company accounts for more than a third of the NAND market, this could translate to a 7.5 per cent drop in global flash shipments. If this was the case, it could cause the price of memory to increase quite significantly in response to reduced supplies.

Even though the facility has backup power systems in place to handle just such an emergency, the voltage drop was apparently so severe that they were overwhelmed. Any wafers currently in production are expected to be ruined, as well as any in storage or transit if the air filtration system that keeps the facility 'clean' was compromised.

The only good news is that Toshiba may be able to partially recover by increasing production during the first few months of the new year, when demand is typically slower.

The full extent of the damage isn't clear at this point, but as the plant returns to full operational capacity Toshiba will begin to evaluate the impact that it has had.

I'm confused, if they had a backup power supply system in place, why didn't it pick up the slack? Those things are meant to handle blackouts, much less brownouts. And why should a brownout halt production for 2 weeks?

This - epic fail. Unless their backup power supply system hadn't been tested properly and didn't have sufficient capacity to handle a blackout? But tbh for something clearly as critical as this, I'd expect them to have an online UPS or similar, so unless someone's screwed up bigtime I'm not really sure what's gone wrong.
Probably wrong but doesnt any UPS take like a couple of milliseconds to actually take over? In this case that 1millisecond caused a great deal of damage, you would have thought they would use a much more thoroughly tested system. I know at the fabrication site in plymouth they always have it well maintained as any power cut is critical.

I agree, how severe can a voltage drop get exactly? The worst it can get is no voltage.
Surely though for a factory that relies on constant, reliable power they should have an online UPS system plus backup generators that can handle the load?

That's what capacitors are for. Hell, you can even use a battery as a capacitor to do the same job. And factory backup power supplies aren't exactly small fries.
