Amount of RAM in the older smartphones and tablets slowly crawled to the level of 3 GB. It will take another year and this mark will surely overcome. This memory manufacturers are interested to reduce the cost of memory chips that can be achieved either by reducing the scale of process technology, or by increasing the crystal capacitance . The second way allows to quickly achieve the desired, and at a lower cost.
Thus, the capacity of crystals mobile LPDDR memory is gradually increased from 1 GB to 8 GB. Last year, the company SK Hynix and Samsung almost simultaneously announced the start of production of 8-Gbit memory chips LPDDR4 and two assemblies on their basis - chips LPDDR4 2 GB and 4 GB. Recently, Samsung has established a new industry record - presented a 12-Gbit memory chips LPDDR4. Of the two, and four 12-gigabit chip can collect crystals LPDDR4 volume of 3 GB and 6 GB. Thus, we can expect that in the next year there will be smartphones and tablets with 6 GB of RAM. It is also worth remembering that the mobile platform, Intel also supports memory LPDDR4, which will integrate capacious chips Samsung's tablet and Intel notebook platforms .
In the production of new products, Samsung is using 20nm process technology class, without disclosing the exact number of technical process. The new devices are characterized by a transmission rate per contact at 4266 Mbit / s - is twice greater than can afford pure standard computer memory DDR4-2133. Also the 12-Gbit crystals 30% faster assembly of 8-Gbit crystals and consume 20% less energy.
