The rapid price increase is due to the economic crisis causing manfufacurers to reduce production, thus reducing supply to keep prices artificially high! They apparently made overly pessimistic predictions for sales during this period and slowed down production. It is the same for almost all components to one degree or another, but RAM pricing has always been more volatile than any other component I can think of...
The diamond industry is the most obvious example of this technique being used repeatedly for decades. Read about how De Beers holds back the diamond stock and releases it as a slow trickle to the Hatton Garden re-sellers:

'Like many aspects of the industry, the way in which rough diamonds are sold is steeped in tradition and tightly controlled. De Beers realised back in the Thirties that the industry had to tread a delicate path between maximising sales and destroying the mystique which justified far higher prices for gem diamonds than for industrial stones, and that the key was co-ordinated action by producers - a cartel, in other words.
Nearly all the world's gem diamonds are mined in a handful of countries - Australia (which produces the most, but also the poorest quality), Zaire, parts of the former Soviet Union and Botswana / South Africa.
So the company persuaded the other diamond producers to funnel almost all their sales of rough diamonds through one organisation, the Central Selling Organisation, run by De Beers. The CSO fixes a set price for its diamonds - no matter what their origin - which varies only according to quality, and attempts to match supply and demand to avoid undermining its price structure.
Primary access to the stones is tightly controlled. Diamonds are offered at 10 'sights' or sales a year in London. Only a limited number of 'sight-holders' are invited - as few as 220 names are on the list, though not all will be asked each time.
Sight-holders cannot specify what they will be offered. When they arrive, they are escorted into a room and given a small packet; a sort of diamond lucky dip containing a mixture of rough stones chosen by De Beers. They cannot pick and choose from this selection; it is all or nothing. What they do not want for their own use they must resell.'
