Memory shrink to 60nm can double production efficiency

Samsung Electronics has announced that it has begun mass producing the industry’s first 1Gigabit DDR2 DRAM using 60 nanometer process technology. In its press release, Samsung estimates efficiency gains of the 60nm process are 40 percent over the 80nm, and twice the productivity of 90nm general process technology.

Samsung’s line up of 60nm 1Gb DRAM-based modules includes 512MB, 1GB and 2GB densities supporting either 667Mbps or 800Mbps speeds. Samsung anticipates such a high degree of receptivity to the 60nm process that it should drive greater demand for 1Gb DRAM chips in the near future over today’s mainstream density of 512Mb.

Samsung’s migration below 90nm has relied heavily on the use of three-dimensional transistor technologies to build increasingly smaller chips, a fundamentally unique approach toward finer circuit designs and higher yields. The use of metal-insulator metal (MIM) for its capacitors provides enhanced data storage in sub-70nm designs. Furthermore, the use of a recently-announced selective epitaxial growth (SEG) technology provides for a broader electron channel, and optimizes the speed of each chip’s electrons to reduce power consumption and enable higher performance. These key technologies are expected to enable DRAM fabrication to 50nm and lower.

Last October, Samsung announced that it had developed a 1Gb DDR2 DRAM chip on the 50nm process. While mass production of the 60nm chips begin now, production of the 50nm process isn’t expected to start until 2008. It won’t be until 2008, however, before the 60nm process becomes the mainstream circuit technology for DRAM. According to Samsung’s forecasts, 60nm DRAM revenues are expected to reach $2.3 billion worldwide in the first year of market availability and to further increase to $32 billion by 2009.

I've noticed a $40 drop in local prices of cheap PC5300 1GIG sticks over the past 3 weeks... which is good to see.

I am curious tho, If 2Gig Modules come down a fair amount in price I'd consider getting them. But, from what I understand XP and Vista 32 can only see 2.7G (if you happen to have 4 or more) so would it even be worth it to put 4G in?

2.7G is the maximum Windows will allow an individual program to use. But the 32-bit OS itself can use upto 4GB, so it would still help with multi-tasking and caching etc.

32-bit versions have trouble with addressing, but from what I understand you can still use all 4GB (just not with one program.) 64-bit will be fine with it.

You guys are missing a few things.

1) The per process limit under Windows 32-bit is 2GB, with a special switch 3GB.
2) In 32-bit OSes you have a 4GB address room. However, address room is also used for hardware resources, add-in cards, etc. So the available RAM gets "cut off" where the hardware resources start, which are traditionally positioned at the end of the available address spectrum.
