Can anyone provide insight as to why RAM prices have skyrocketed recently?

This is getting ridiculous. It seems in the last week, sets that were $59 are now $82, and sets that were $64 are now $96. Is there something that is going on that we need to be informed of?

Couple of things a IC fabrication factory burned up, a IC company folded and all the DRAM makers are starting to gear up for DDR4 so lower production, but demand still high
