DDR4 Memory Prototypes Demostrated at ISSCC

By - Source: XbitLabs | B 5 comments

Two DDR4 memory modules were shown off at this years ISSCC.

With DDR4 DRAM set to hit the market in 2013, two manufactures took the opportunity at this years International Solid-State Circuits Conference (ISSCC) to demonstrate their DDR4 DRAM. It is expected that DDR4 will represent 50 percent of the market by mid-2015, after its initial launch on the server side in 2013.

DDR4 is set to have a data transfer rates of 2133 MT/s to 4266 MT/s compared to 800 MT/s to 2133 MT/s of DDR3. DDR4 is also expected to have significantly lower voltage requirements than DDR3. It will require between 1.05 V to 1.2 V to operate, whereas DDR3 requires between 1.2 V to 1.5 V. The lower voltage requirement is expected to reduces power consumption by 40 percent compared to a 1.5 V DDR3 module. DDR4 will not be pin compatible with DDR3, which means they will not be backwards compatible.   

Samsung's DDR4 DRAM module can achieve data transfer rates of 2133 Gb/s at 1.2V, compared to 1.35V and 1.5V DDR3 DRAM at an equivalent 30nm-class process technology, with speeds of up to 1.6 Gb/s. Hynix's DDR4 device works at 2400MHz (2400 Mb/s) at 1.2V and processes up to 19.2 GB/s of data per second with a 64-bit I/O. Hynix used its 38nm manufacturing process technology, while Samsung employed the 30nm node instead.

Other manufacturers such as, Elpida, Micron and Nanya, didn't show off their DDR4 prototypes but are expected to by end 2012. With DDR4 set to hit the PC enthusiast market in 2014, are you going to make the jump to DDR4 or wait until it becomes mainstream much like many users did with the switch from DDR2 to DDR3?

    So this means by 2013 we will all have to replace our mobo if we want to upgrade our ram?

    DDR3 will still be available for a long time, so you'll be able to buy larger/faster modules as needed, though of course they won't be as fast as DDR4.

    its unlikely they will be supported on any current platform. the first 1st enthusiast builds to do so will probably be a haswell based setup... i would guess its unlikely to be available to sandy users. ivy may well have support for it but thats just a guess on my part... seriously i cant honestly see it on 2011 socket platforms.
    if history is anything to go by prices are likely to be ridiculous at launch much like ddr3 was for the first 2 years.

    More likely to be available on next gen graphics cards before anything else.

    If you can find an application able to saturate existing mainstream memory, and the gains are significant, then sure.. but how much does it cost?

    I'd rather have tons of slower RAM than a small amount of faster, more expensive stuff even if I'm using more power.
