Think the 3GB of RAM in the Galaxy Note 3 was a lot? Samsung was only getting started. The company has just unveiled the first 8-gigabit (1GB) low-power DDR4 memory chip, which could lead to 4GB of RAM in a multi-layered, mobile-sized package. Moving to the higher-bandwidth (3.1Gbps) DDR standard should also provide a hefty 50 percent speed boost over existing DDR3-based chips, even though the new silicon uses 40 percent less power than its ancestors. Samsung is only promising mass production of the new RAM sometime in 2014, but it's already clear about the target audience. The technology will go into laptops, smartphones and tablets with Ultra HD displays, where additional memory will be crucial for powering all those extra pixels.
