512MB modules are built using either 128-Mbit DRAM or 256-Mbit DRAM. The former has twice the number of DRAM IC over the latter. Due to the higher density DRAM, there is a significant increase in cost. Since Corsair uses 256Mbit DRAM, their 512MB modules cost a lot more.
When you see a much cheaper 512Mb modules, that is because it is built using 128Mbit DRAM.
