1Gb DDR2 modules shrunk by Samsung

36 percent smaller than predecessors

Samsung has started mass-producing 1Gb 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 80nm (nanometre) process, will be 36 percent smaller than their predecessors, which were produced using a 90nm technology, the company said today.

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 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 80nm process. It has been mass-producing 512Mb chips using an 80nm process since March, it said.
