Chinese officials, citing "massive evidence," have accused Samsung, Micron, and SK Hynix of colluding and fixing the price of DRAM. If the allegations are true, the three largest DRAM manufacturers in the world would be directly responsible for the massive price increase for DRAM over the past few years. This isn't the first time these three companies have been accused of price-fixing. Back in 2005, all three pled guilty to similar charges levied by the US Department of Justice.

About time! While ram prices have been dropping slightly recently, they are still far too expensive. I miss the day I bought 16gb of ram for 35 bucks.
