Cheaper 4GB 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.

As memory requirements grow, Samsung expects “global DRAM market is worth US$28.7 billion this year and predicted that will rise to US$37.8 billion by 2008. The 1Gb DRAM currently represents 8% of total market share, but is expected make up 36% of all DRAM sold in 2008. “

It is unknown how long it will take memory manufacturers to start releasing 80nm 1Gbit memory equipped modules, though demand might not be high enough till Microsoft releases Windows Vista. Samsung spoke with DailyTech earlier this year about the increasing demand of memory by the operationg system, especially with Vista in 2007.  With the median system memory amount on the rise, it isn't too outlandish to expect all new systems to push 1GB and 2GB of on-board memory by this time next year.
