Elpida Develops 4-Gigabit DDR2 Mobile RAM Operating at 1.2V and 1066Mbps

Elpida Memory, Inc., Japan's leading global supplier of Dynamic Random Access Memory (DRAM), today announced that it has developed a 4-gigabit DDR2 Mobile RAMTM that employs state-of-the-art 30nm process. This new Mobile RAM features a low operating voltage of 1.2V, achieves a 1066Mbps high-speed data transfer rate, and uses roughly 30% less operating current compared with stacking two of Elpida's 40nm 2-gigabit products. Through sophisticated circuit design and advanced process technology, this product achieves the world's smallest class in chip size for a 4-gigabit LPDDR2. In addition, it is an eco-friendly DRAM equipped with a low power feature that targets mobile devices such as smart phones and tablet PCs by contributing to extended operating times of battery-powered devices.

Currently, the rapidly expanding market for smart phones and tablet PCs is striving to expand the features of its operating systems. As a result, the ideal density of DRAMs is also rapidly on the rise, and there is an increasing need for high density DRAMs – 8-gigabit for high-end smart phones and 16-gigabit for high-end tablet PCs. At the same time, there is a strong demand for smaller, thinner, and lighter DRAM packages, and attention is being focused on advanced package technologies such as Package on Package (PoP) and Multi Chip Package (MCP).

Elpida plans to ship the new DDR2 Mobile RAM as PoP, FBGA packages, and as a bare chip for MCPs. The company's PoP and FBGA packages fully leverage die-stacking technology to provide an extensive line-up of 8-gigabit to 16-gigabit products that can meet a variety of customer needs. The new 4-gigabit DDR2 Mobile RAM achieves the thinnest package yet at 0.8mm (in the case of an 8-gigabit product consisting of two stacked 4-gigabit chips), which meets the need for DRAM that is not only higher density, but also thinner packages.

Sample shipments of the new 4-gigabit DDR2 Mobile RAM will begin in April, and mass production is scheduled to start at Elpida's Hiroshima Plant in June of this year. Production is also planned at Rexchip Electronics Corporation in order to guarantee a stable product supply.

Elpida, a leading provider of DRAM for mobile devices, uses advanced technology to support the development of the next generation of smart phones and tablet PCs.

Did nobody tell Elpida we've switched to DDR3 by now?

Desktops have moved to DDR3 but mobile devices like tablet PCs and smartphones still largely use DDR2 because its cheaper.

True...

But this press release did mention they planned to use it in smart phones as for everything else. I agree...Netbooks/ipads/eepads/ and laptops/notebooks have been making the change to DDR3 a long long time ago.

That asside, This is still low voltage DDR2 at 1.2v so battery life of your portable devices will be a little longer.

yes, LPDDR2

But really, I see no point of 4GB on tablets or smartphones. If indeed a time comes when Android OS uses 1GB RAM like Win7, I'll be damned.

Famous past words... What was it, 64k is enough for all of us?

shouldn't smartphones switch to DDR3 so they can make ultra low voltage DDR3 that saves even more battery life?

Am I correct that this is 512 MB (ie: 4Gb = 512MB)?

I could see a smartphone using more than 256MB of RAM, so 512MB isn't useless IMO :)
