Samsung pushes 'green' 30nm memory

Could it make cloud computing a reality?

Samsung's components division is pushing the eco-friendly angle at CeBIT this year (just as it did last year). The difference this time around is that the company believes its reduced-power-consumption 30nm DDR memory could hold the key to the future of cloud computing.

Following on neatly from the Cloud Computing Summit, at which a number of the panellists spoke of the infrastructure obstacles facing the concept, Samsung was today showing off its 30nm Green DDR3 2 gigabit (Gb) and 4Gb memory. The firm says this RAM will allow datacentres to handle the excessive workloads of fully fledged cloud computing.

Samsung had set up a working model with standard 50nm DDR3 memory on the left and its two flavours of 30nm Green DDR3 on the right. A readout showed that while the 50nm setup was burning 100W, the 2Gb and 4Gb models were using just 60W and 40W respectively, more than halving the energy usage.

As well as reducing power consumption, the 30nm memory keeps operating temperatures lower. While the 50nm memory ran at around 59 degrees Centigrade, the 30nm setups hovered around 53 and 50 degrees respectively.

All of which is good news for servers and datacentres groaning in anticipation of the workload they will face as we all start living our lives in the cloud. And the word 'green' isn't really the key here: for me the selling point of this technology is clearly lowering energy bills rather than saving the planet.

Nevertheless it's hard to escape the impression (although perhaps this is being overly cynical) that for all its undoubted innovation, Samsung is somewhat prone to bobbing with the prevailing currents, marketing-wise; the theme of this year's CeBIT was always supposed to be the cloud, and so Samsung's memory is the saviour of cloud computing. Last year everyone was talking about the environment, so a distinctly similar concept (alongside a number of related initiatives, admittedly) was pressed into the service of planetary salvation.

Still, we're looking forward to living in the cloud, so anything that could help to make that dream a reality is alright by us. Samsung told us that its green memory is already being used in Fujitsu servers, and it will roll out further flavours over the course of this year. The company said it will reveal further details of its green memory plans in April.

It’s perfect for mobile workers. Just take it out — it’s small enough to sit anywhere — turn it on, load a sheet of paper, and start printing.
