While perhaps not as resilient as the 3.5-inch floppy disk, DDR2 is doing its damnedest to avoid obsolescence. The only trouble with that is that memory chip makers aren't showing much interest in prolonging DDR2's relevance in the market place, not when faced with steep drops in contract quotes for DDR2 chips.
Just about every DRAM maker has shifted their capacity to the production of DDR3 chips, and in some cases (like with Powerchip Semiconductor Corporation), production is so lopsided that shares of DDR3 wafers have climbed above 70 percent. That's a big change from the third quarter of 2009, when PSC's DDR3 production sat somewhere between 0-5 percent of overall output.
But PSC isn't the only one. Both Nanya and Inotera Memories have also ramped up DDR3 output. And according to DRAMeXchange, Nanya is likely to see DDR3 consume 90 percent of the company's production.
