Computer memory has come a long way. RAM continues to grow up, even as the price goes down. Companies have continued to offer far more RAM for far less cash each year. On average, the cost of a megabyte of RAM drops approximately 40 percent each year. Unlike the CPU and hard-drive markets, which are dominated by a small number of manufacturers, the memory market is extremely competitive, with dozens of vendors selling modules produced by a wide variety of chipmakers. Although there are respected leaders, no one company calls the shots in the mainstream RAM business. Some what it acts like promotional tactics too as DDR2 RAM can't be placed on DDR1 capable motherboard. So people need to upgrade their motherboard too. Anyways DDR1 isn't becoming obsolete yet and it'll take sometime to entirely replace it by DDR2. Till then, we can see the DDR2 going to cost much lesser than it's predecessor. But prices will be hiked once it becomes mainstream.
