Samsung Electronics has started mass-producing 1 G-bit DDR (double data rate 2) DRAM memory chips using an advanced manufacturing process that allows it to make the chips smaller and at less cost.
The chips, manufactured using an 80 nanometer process, will be 36 percent smaller than their predecessors, which were produced using a 90-nanometer technology, the company said Tuesday.
The figure refers to the size of the smallest feature on the chip. Smaller features mean a greater number of chips can be produced from a silicon wafer, lowering production costs.
Most 1G-bit DRAM chips today are stacked in high-capacity modules for high-end servers. Thirty-six 1Gb DRAM chips are used for each 4G-byte module.
All of Samsung's DDR2 chips are now manufactured using an 80-nm process. It's been mass-producing 512M-bit chips using an 80-nm process since March, it said.
