By applying 80nm process technology, Samsung will produce the world’s smallest DRAM package (11x11.5mm). This is 36% smaller than the 11x18mm package required for a DRAM chip utilizing 90nm and nearly as small as the 512Mb DRAM, which is half the size of a 90nm 1Gb chip.
Most 1Gb DRAM chips today are stacked in high-capacity DRAM modules for next-generation servers. These modules include the 4GB fully buffered Dual In-line Memory Module (DIMM) and the 2GB Small Outline Dual Inline Memory Module (SODIMM).
Thirty-six 1Gb DRAM chips are needed to create a 4GB module, which has had to be configured either by stacking two chips on top of one another or by enclosing two chips into the same package. Avoiding chip stacking simplifies the production process, lowers production costs and enhances overall electrical properties.
The market research firm Gartner estimated that the 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.
Samsung is now producing all densities of DDR2 DRAM at the 80nm node. It began producing the first 512Mb DDR2 DRAM at 80nm node since last March.

Samsung Develops World's First Eight-Die Multi-Chip Package Technology for Multimedia Cell Phones
Samsung Electronics Co., Ltd., the world leader in advanced memory technology, today announced that it has developed the world's first eight-die
multi-chip package (MCP)
technology, designed for use in high-capacity mobile devices such as 3G handsets and other increasingly smaller mobile devices.
Typically, as the number of chips per memory package increases, so does the thickness of the package. Using its Wafer Supporting System technology to make wafers thinner during design processing, Samsung has been able to minimize overall die thickness as well as decrease the space between the stacked dies. As a result, the eight-die MCP solution offers an unmatched combined capacity of 3.2 gigabits in a package that is 1.4mm thick, equaling the thickness of a four-die MCP solution.
