Think 4GB RAM in your new phone is overkill? Get ready to see 6GB modules make their way into smartphones in the near future, as Samsung has announced mass-production of 12Gb LPDDR4 DRAM modules. 12 Gigabits translates to 1.5 Gigabytes (GB), with four DRAM chips stacked together leading to 6GB of RAM.
The development also means that devices which feature two DRAM chips will be able to offer 3GB RAM instead of 2GB RAM. Samsung's earlier manufacturing process yielded 8Gb modules, but the manufacturer is now able to offer 50 percent more density using the same 20nm node.
The higher density means that a 6GB module using 12Gb DRAM would take up the same amount of space as a 3GB RAM module with 6Gb chips. The new DRAM is also significantly faster, with a quoted 30 percent increase in speed combined with a 20 percent reduction in energy usage.
Samsung has not so subtly hinted that its next-generation flagship smartphones will offer 6GB RAM, so we may not have to wait long for a phone with more RAM than what is commonly found on notebooks today.
