Samsung has started mass-producing the most advanced memory chips to date, clearing the path for smaller and cheaper processors.

The 1Gb DDR2 DRAM chips use an advanced 80nm manufacturing process and will be 36 percent smaller than their predecessors, produced using a 90-nanometer technology. Smaller features mean a greater number of chips can be produced from a silicon wafer, lowering production costs.

Most 1Gb DRAM chips today are stacked in high-capacity modules for high-end servers. Thirty-six 1Gb DRAM chips are used for each 4GB module. All of Samsung's DDR2 chips are now manufactured using an 80-nm process. It's been mass-producing 512Mb chips using an 80nm process since March.
