One out of the two Micron's DRAM plants is out of production after they had to close it down after a nitrogen gas dispensing system. That malfunction contaminated equipment and wafer production. The plat is responsive for nearly 6% of the world market production of DRAM.

As long as the plat remains out of action, there will be disturbance in the force, pardon the pun. And that would be demand versys supply and thus prices. DRAM prices already have been under a lot of stress due to high-demand and low production, priced have nearly double since a year ago. 
 

This new incident certainly is not going to help. The DRAMeXchange estimates that Micron Technology Taiwan, also known as Inotera, is missing around 60,000 wafer starts per month as a result of all this. And that is a conservative estimate. Micron's Inotera factory DRAM is used in products for PCs, servers and mobile devices.
 

Above a year spread price on for example a Corsair Vengeance LPX 16GB DDR4-3200 CL14 kit

 
Inotera is "mainly responsible for manufacturing Micron’s LPDDR4 products that go into Apple’s supply chain for iPhone" as they state though. That menas it could even have an effect on the upcoming iPhone 8 launch window and availability. Micron should have Fab-2 up and running at full capacity again ASAP. 

DRAM Prices Might Go Up Again As MIcron Plant Has Issues
