Samsung Electronics, being the ultra HD 4K pioneer that it is, has been busy developing the technology necessary to make 4K graphics in the next waves of smartphones (such as its own) work smoothly and powerfully. Currently, amongst other projects, they’re building the DRAM technology necessary to make 4K workable in the smartphones of the next year and beyond.

The company just recently announced that it is starting mass production of what is called the LPDDR4, an industry first and one of the most advanced new RAM chips to come into existence yet.

The first mass-production line of these chips are being built on a 20 nanometer process and designed to deliver an initial 2GB of DRAM but to also soon scale well upwards to a 4 chip SoC (System on a chip) stack that offers a whopping 4GB of DRAM power inside the flagship smartphones released for that year. This is at least 1GB more than the RAM available to any mobile device on sale today.

For the next year at least, this LPDDR4 technology in chips will be the state of the art in the industry and is expected to deliver enormous savings in terms of cost, memory density and power usage in the latest smartphones and possibly even tablets that will come out over the following months.

Furthermore, Samsung isn’t alone in producing LPDDR4 chip technology. At least two other companies –Micron Technology, Inc. of Idaho and SK Hynix Inc. are both working on the same development, although neither has reached the mass production stage as Samsung has.

As far as consumers are concerned, the most obviously visible benefits of the arrival of this new type of DRAM chip technology will be an increase in the number of phones that offer 4GB RAM packages and the arrival of phones with more 4K related graphics capabilities.

This second consumer benefit is actually one of the core reasons why Samsung has been working on LDDR4 technology: As Samsung’s EVP of memory sales and marketing, Joo Sun Choi has said,

“By initiating production of the 2nm 8-gigabit LPDDR4, which is even faster than the DRAM for PCs and servers and consumes much less energy, we are contributing to the timely launch of UHD, large screen flagship mobile devices”.

In other words, the new DRAM technology being pioneered by Samsung is directly aimed at allowing ultra HD screen displays in 2015’s smartphones and tablets and it’s expected to deliver exactly that benefit.
