Elpida Memory, Inc., Japan's leading global supplier of Dynamic Random Access Memory (DRAM), today announced the DRAM industry's first-ever use of high-k metal gate (HKMG) technology to develop a 2-gigabit DDR2 Mobile RAM (LPDDR2) at the 40nm-class DRAM node.

HKMG is technology that uses insulator film with a high dielectric constant (abbreviated to "high-k," a semiconductor industry measure of how much charge a material can hold) in the transistor gate to reduce current leakage and improve transistor performance. Metal gate electrodes that are required for the high-k dielectrics process are also used. Some makers of logic semiconductors have started to use HKMG, but higher heat treatment temperatures after HKMG formation and complicated DRAM structural characteristics have prevented consistent application in the DRAM fabrication process. Elpida, however, has managed to lower the heat treatment load and overcome certain memory device structural complications.

Good stuff this has been needed for such a long time.
Might be a bit late as the All-In-One pc's is likely to die out or get useless hardware.

Would be good if all memory made for both desktop and laptop is sodimm sized, built for mobile tweaked for desktop heat / power in a desktop. Low power when laptop needed, OC'd laptop specs for Desktop use. This should leave a larger margin for Desktop overclocking / over volting.

Hopefully they could then focus all efforts on sodimm sized ram and produce better hardware / more dense memory chips like this 2gb Elpida and get the laptop / desktop ram to tech evolve much faster.

There is no reason why a sodimm should not perform the same or better than a desktop dimm.

Same for laptop + desktop gpu / cpu, build for mobile hot-rodded for desktop with loads of heat and power space for oc'ing on a desktop. :toast:

Why DDR2 RAM and not DDR3 RAM?

Mobile as in Tegra III, phones, handheld gamers, non x86 based tech. Although would be great for mainstream and enterprise systems.
