Samsung starts mass production of 6GB DDR4 modules for smartphones

Samsung has started mass production of 12Gb chips lpddr4 dram. The chips can be used for modules of 3GB or 6GB. Samsung makes the chips on its existing 20nm-class process, but manages to use this production method more efficiently.

Samsung already makes 8Gb chips lpddr4-dram on its 20nm-class production process, but the group is now also able to mass-produce 12Gb chips. This allows Samsung to combine two or four chips on a package for 3GB and 6GB modules for tablets and smartphones respectively. Currently, Samsung makes lpddr4 modules of up to 4GB.

The lpddr4 memory works at 4266Mbps, 30 percent faster than Samsung’s 8Gb lpddr4 chips. At the same time, consumption compared to the 8Gb chips would be 20 percent lower.

According to the Korean group, the 6GB packages will come to “flagship” smartphones of the new generation, but which mobile devices will be equipped with the amount of memory, the company does not say. Incidentally, Samsung’s 20nm-class process means that the chips are baked in a production method of somewhere between 20 and 30nm.
