Lots of bankruptcies, buyouts and mergers by memory makers, and the remaining players have figured out how not to slash each other's throats based on what the OEM's are willing to pay. Our (retail) price is a reflection of that. It's still not bad, $.30/meg for DDR- It was $1.00/meg after the Taiwan earthquake for SDR, at a time when there was actually a glut on the market. Reamage Extremeage, lots of middlemen bought new Mercedes and summer homes in the country.
The current situation can be regarded in terms of market consolidation or collusion in restraint of free trade, take your pick. Just guessing, but I would expect the price to come down slightly over the next 6 months, but the days of really cheap memory are over for now.
