Intel won't be moving to a new memory platform until at least 2014, meaning DDR3 is here to stay for now.
The upcoming Ivy Bridge series of processors from the chip giant is fully compatible with DDR3 and its 'tock' cycle Ivy Bridge E - set for release towards the end of 2012 - will also stick with the time honoured standard.
However, once we push into 2013, we will see some minor changes, with the introduction of a lower powered memory known as DDR3L which will have a maximum voltage of 1.5v. This will be supported by the Haswell processor that is likely to show up sometime in the first half of 2013, most likely in the second quarter.
Once we get into 2014, we might see the fourth generation of DDR memory supported by Intel Broadwell processors, but even at that stage it's only a maybe. Memory bandwidth is not a big limiter in computing at the moment, so there's no reason to rush through something that won't be of much benefit.
DDR3 memory has now been around since 2007, introduced for the first time along with Intel's supportive Bearlake P35 chipset. It offered big reductions in power requirements over previous generation DDR2, as well as a nice jump in overall bandwidth.
