At Uplinq I met representatives of Samsung who are promoting the LPDDR3 memory designed for the next-generation smartphones and tablets. LPDDR is also known as “mobile DDR” and it is a type of memory that can consume 10X less power in standby mode, when compared to typical “PC” DDR3 memory. Obviously, this is a big deal because most of the time, your smartphone is in standby mode, doing very little. Many smartphones currently use LPDDR2.
This type of memory consumes less power because they have a special design which requires a lower voltage, a slower refresh rate and they also have a mode where they don’t even have to keep their content. The design works for mobile devices, but the extra cost is not justifiable (yet!) on regular PCs and laptops which have components that consume much more juice anyway (display, CPU, GPU). (more…)
