Why has ram prices doubled since last year

i was thinking of selling my two 4GBs and getting two 8s but i saw a graph and it seems like the prices have doubled since last year. why is that? is it gonna go back down?

If your using DDR3 their going up because of supply and demand.
The new hardware uses DDR4 so their putting their resources their.
It's like the price of the old DDR2 their crazy expensive.
