I think I've reported this number before, but I keep forgetting it. Anyway, there is a statistic suggesting that memory components eat up something like 15 percent of the power consumed in data centers. Not an insignificant amount, which is one reason Micron continues to focus on lower voltage as a product differentiator. It latest additions to the energy-efficient Aspen Memory line are a 1-gigabyte DDR3 module that operates at 1.35 volts and a 2-gigabyte DDR2 module that runs at 1.5 volts. The Boise, Idaho, company says these are the lowest-voltage DDR2 and DDR3 designs available on the market. (Normal voltage ranges for DDR3 are 1.5 volts, while DDR2 modules typically run at 1.8 volts.) So, for example, Micron claims... ...
