Samsung Electronics has started mass-producing 1-gigabit 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 1-gigabit DRAM chips today are stacked in high-capacity modules for high-end servers. Thirty-six 1-gigabit DRAM chips are used for each 4GB module.
All of Samsung’s DDR2 chips are now manufactured using an 80-nanometer process. It’s been mass-producing 512-megabit chips using an 80-nanometer process since March, it said.
