Smartphones have been ahead of laptops and desktop PCs in terms of the amount of RAM on board for several years now. Samsung has decided to further widen this gap. For future premium class devices it 16GB LPDDR5 DRAM chips.
Samsung's new record-breaking capacity memory chips consist of 12 stacked crystals. Eight of them have a capacity of 12 Gbit, and four have a capacity of 8 Gbit. In total, there is one memory chip with a capacity of 16 GB. Obviously, if all the dies in the stack were 12 Gbit, Samsung would introduce an 18 GB chip, which it will likely do in the foreseeable future.
The Samsung chip with a capacity of 16 GB is made in the LPDDR5 standard with a throughput of 5500 Mbit/s for each data bus pin. This is approximately 1,3 times faster than LPDDR4X mobile memory (4266 Mbps). Compared with the 8 GB LPDDR4X chip (package), the new 16 GB LPDDR5 chip, against the backdrop of doubling the volume and increasing the speed, provides a 20% saving in consumption.
Note that the 16 GB LPDDR5 chip is assembled from memory crystals produced using the second generation of the 10 nm class process technology. In the second half of this year, at a plant in South Korea, Samsung promises to begin mass production of 16-Gbit LPDDR5 crystals using the third generation of the 10 nm class process technology. Not only will these dies have the highest capacity, but they will also be faster, with a throughput of 6400 Mbps per pin.
Modern premium smartphones and smartphones of the near future, Samsung is confident, will not be able to do without an impressive amount of RAM. Smart photography with expanded dynamic range and other features, mobile games with stunning graphics, virtual and augmented reality - all this, supported by 5G networks with increased bandwidth and, more importantly, reduced latency, will require faster memory growth in smartphones, not PCs.
