We have new acronyms that will soon begin to sound everywhere. With the new generation of smartphones in the MWC 2015 have come UFS 2.0 and DDR4, two new standards of memory you are already present in the new phones.

For now on top, more high-end models, but that insurance will be coming to the rest of families. according to itypejob.com,UFS 2.0 is a new standard for flash storage extremely fast; on the other hand, DDR4 is the fourth generation of memory RAM ‘DDR’, sure I sound much more.

UFS 2.0, the memory of the present and the future

UFS, or Universal Flash Storage, It is intended to be the new standard of memory for phones, cameras and other electronic devices. The successor to the eMMC, so far the single market and implemented by virtually all.

UFS 2.0 It is the second generation, and will be the best known. The first version (UFS v1.1) was published in June 2012 and was rapidly advanced by UFS v2.0, released in September of 2013 by the JEDEC under code JESD220B. It was not until 2014 when some manufacturers announced that they would begin to implement it, and it is now 2015 when users of a foot can enjoy it on end devices.

What are the main features of UFS 2.0? It’s an evolution in various aspects on eMMC 5.0, improving aspects such as available bandwidth, new extensions to safety or energy management. An interesting fact is that UFS 2.0 allows the simultaneous read/write, while eMMC allows only one or the other, but not both at the same time.

Much more interesting is the quantitative improvement UFS 2.0 provides front eMMC 5.0. An example: eMMC provides a bus up to 400 MB/s, while UFS 2.0 HS-G2 offers twice, up to 742 MB/s based on two lines of 2.9 Gbps. In the standard, there is also a superior version, called HS-G3, and brings two lines to 5.8 Gbps that could reach 1,485 MB/s.

Here above described the theoretical data provided by UFS 2.0 standard. In the harsh reality, how not, are figures significantly lower. Samsung, one of which most are betting on UFS 2.0, gave some data on sequential steps that are usually much closer to actual use

eMMC 5.0 2013 250 90 7000 13000
eMMC 4.5 2012 140 40 1500 500

(*): eMMC 5.1 is the new generation that has been announced in February 2015, and whose availability in the market is expected to face at the end of year.

Equally interesting are some benchmarks as the filtered by PhoneArena, where proposed a improvement of between 1.4 and 4 times the performance of past generations smartphones.

However, there are not only benefits in favor of UFS 2.0. Its big disadvantage against eMMC is that it is a more expensive memory, which restricts its current usage to high-end devices. Industry expects a decreasing trend in its price, so that in the coming years we will see her in the rest of ranges.

LPDDR4 is the new RAM for the best mobile

Unlike UFS, LPDDR4 maintains a ‘traditional’ evolution. It is the new standard of RAM that will be gradually adapting to smartphones and tablets from any manufacturer, for now – as usual – in the high to later go down to all other products ranges.

LPDDR4 standard – Low Power DDR – was published on August 25, 2014, as an evolution of the already more than usual LPDDR3. A new generation of RAM memory which improves several sections of previous versions, including the clock frequency which happens to 1,600 MHz. or the ratio of transfer, which improves proportionately to the 3200 MT/s. also is also given a decrease in voltage that it will affect lower consumption, even though it is a timid reduction from 1.2 to 1.1 volts. Then we capture the main changes with respect to the current LPDDR3:


Freq. Internal 200 MHz. 200 MHz.
Freq. Watch 800 MHz. 1600 MHz.
Ratio of transfer 1600 MT/s 3200 MT/s
Voltage 1.2 ~ 1.8 V. 1.1 ~ 1.8 V.

As with UFS, Samsung is positioning itself as one of the leaders in DDR4, having already presented its first modules in December 2014. This presentation also provides some other details: these first generations of memory LPDDR4 are being manufactured in modules of 1 GB and with 20 nm architecture; the manufacturer ensures, in addition, that They provide twice the performance and density than LPDDR3.

Obviously LPDDR4 improve the performance of our smartphones, as we could not expect anything else. However, what degree or proportion? What will be better it we will notice the users? There are no benchmarks in this respect as there is only a phone that includes this technology.

Galaxy S6, for now the only one who enjoys UFS 2.0 and LPDDR4

And it is that UFS 2.0 and LPDDR4 are only present in the Galaxy S6 and S6 Edge, two beasts that surely has had everything to do it’s own Samsung one of the main architects of the new standards, In addition to manufacturer.

A priori Samsung Galaxy S6 will be a small pasito ahead of the competition Thanks to the new versions used in storage (UFS 2.0) and RAM (LPDDR4). What will be the impact of the new standards in the overall performance of the phone? It is very difficult to determine taking into account that also coexist alongside other changes such as the processor, an Exynos 7 Octa 7420. Rather they will influence, sure, but I’m afraid that until we have new phones in hands I would not dare to give me in this regard.
