Elpida 50nm DDR3 RAM
Elpida says it has expanded its lineup of DDR3 RAM with what it says is the most energy-efficient memory of the type. A new format based on a 50 nanometer manufacturing process helps both reduce the size of each chip to 40mm (1.6in) square and also reduces the amount of power necessary to drive the memory. Where most DDR3 needs 1.5 volts, the new memory can scale back to 1.35V or even 1.2V in notebooks, servers and other low-profile computers that may not run at full power.
The new DDR3 memory also scales up to adapt to future versions of DDR3 that run up to 2.5GHz in addition to speeds for existing systems, whose memory tops out at 1.6GHz on current Intel Xeons. Elpida plans to build its 50nm RAM from early 2009 and also says it should carry the technology over to high-end home electronics and mobile devices.
