Elpida Memory, Inc., the Japan-based third largest Dynamic Random Access Memory (DRAM) maker in the world, today announced it had completed development of the industry's first 25-nanometer (nm) process 4-gigabit DDR3 SDRAM. The new chip is also the smallest 4-gigabit DRAM. The new cutting-edge smallest available 4-gigabit chip uses ultra fine-width 25nm process migration technology. Back in May, Elpida finished development of a 2-gigabit DDR3 SDRAM using the advanced 25nm process and began sample shipments in July.

By using ultra-fine process technology the 4-gigabit DDR3 SDRAM becomes a more energy efficient chip and achieves higher productivity. As a 4-gigabit product, its density is double that of Elpida's 2-gigabit DDR3 SDRAM based on the same process node. The newly developed 4-gigabit DRAM enhances productivity by about 45% compared with Elpida's 30nm 4-gigabit DDR3 SDRAM. Compared with this same 30nm DDR3, it reduces operating current by about 25-30% and standby current by about 30-50%. It has also realized the industry's highest speed data transfer rate.

DRAM is the indispensable working memory for supporting information processing in personal computers, mobile phones and many other kinds of electronic appliances. In recent years, there has been an explosive increase in demand for solutions to instantaneous processing of music, pictures, video and other high-density data. DRAMs used in those applications must be capable of not only faster speeds but also lower power consumption.

The new 25nm DDR3 SDRAM is expected to find applications in PCs and in servers used in data centers and other facilities that perform large-scale information processing tasks. Other applications are likely to include tablet PCs and UltraBook (an ultra-thin notebook PC).

Elpida, a leading company in the DRAM industry, is focused on design and development of high-density and low-power DRAMs. As a leading provider of memory solution company, Elpida is committed to provide the most advanced products.

Sample shipment and mass production of the new 25nm 4-gigabit DDR3 SDRAM is expected to start by the end of this year.

interesting that they went 25nm, right as samsung went 20nm

Was thinking the same thing, won't the 20 nm be a preference?
depends, normally lower is better, but sometimes different architectures can completely eliminate the gap between manufacturing tech

That was 20 nm class, not 20 nm. 20 nm class is something in the range of 20~29, in reality, it's 25 nm.

This sounds good. This company has come a long way. $$ Elpida stock price jump ahead $$ :toast:

This should guarantee Elpida a few new contracts with Apple seeing Apple and Samsung has "who has the biggest chipolata contest" issues.

Any idea where they manufacture, Mexico ? and far east ? Brazil ?
TSMC or in house or mixed ?

Sry I have not kept up with their history / evolution. :eek:

It also depends on how hard hard / easy they are to make, a smaller process is no good, if you can't keep up with the demand for the product because it's soo hard to make.
