Cheaper 4GB DDR2 modules on the horizon?
 

Samsung has announced it will be mass-producing 80nm 1Gbit DDR2 memory chips. Current 1Gbit memory chips are produced on a 90nm fabrication process and about 11x18mm in size.

New 80nm 1Gbit memory chips will be 11x11.5mm and will have a physical package nearly the same size as 512Mbit 90nm chips. In addition to the smaller size the 80nm 1Gbit memory chips will also be cheaper to manufacturer, thus lowering overall costs for 2GB and 4GB DDR2 modules. 1Gbit modules are typically arranged in kits of 16 pieces on a single PCB to give us 2GB memory DIMMs.
