The DDR4 RAM operates at a lower voltage of 1.2 volts as compared to DDR3’s 1.5 volts. Power consumption is another aspect which manufacturers like to minimize, and thanks to the new DDR4 RAM, it works out quite well for them. This has been made to make the routing process easier. Additionally, the PCB has been made thicker as well, raising the dimensions from 1.0mm on the DDR3 to 1.2mm now, which opens the scope for more signal layers. To accommodate the added pins, the modules have a raised height of 31.25mm, as compared to DDR3’s 30.35mm. This further decreases the overall per-pin contact as well. Furthermore, since the modules are of the same length, the pin-to-pin distance in the DDR4 RAM has been brought down to 0.85mm, as compared to DDR3’s 1.00mm. DDR4 has switched to a 288-pin package, which directly goes on to say that there will be an obvious boost in the bandwidth capacity, which we will discuss further in the article. The DDR3 RAM used a 240-pin package, that has been changed in the DDR4 RAM. To make the jump to newer technologies, the design is probably the first thing that has changed.
