Samsung has announced what will start manufacturing USF 4.0 memories for smartphones and other devices. The South Korean manufacturer claims that the implementation of the new standard has resulted in “the highest performing Universal Flash Storage solution in the industry”, with speeds twice that of mobile memories currently on the market.
First of all let’s see why this standard is important. In the increasingly digitized world in which we live, we use our mobiles for a large number of tasks. From recording videos in ultra high definition to enjoying games and listening to music. For all this we need a storage system capable of offering good read and write speeds.
But not just any storage solution will do. In addition to good performance, priority must be given to reduced space and energy efficiency, after all we are talking about mobiles, where these features are key. This is precisely where UFS storage memories come into play.
The most advanced memories are on the way
Over the years, the USF standard has gotten better, not just in capacity, but in performance as well. Samsung, which has already released several smartphones with previous versions of UFS and one of the members of the Solid State Technology Association (JEDEC), has finished the tasks of implementing the UFS 4.0 standard and is ready to start production at large scale of this type of memories.
Samsung claims that UFS 4.0 offers a speed up to 23.2Gbps per rail, that is, almost twice as much as UFS 3.1. The South Korean company ensures that this transmission speed is ideal for 5G phones, which require a large amount of data processing. Furthermore, he sees a future where it could also be adopted in automotive applications and virtual reality and augmented reality devices.
Let’s get to the more technical details. The implementation of the standard by Samsung will be done with its 7th generation V-NAND memories with the well-known interface called full duplex, which can read and write data simultaneously, and a proprietary driver. This will guarantee, they claim, read speeds of up to 4,200 MB/s and write speeds of 2,800 MB/s.
Regarding energy efficiency, a key feature for the battery life of devices, Samsung ensures that UFS 4.0 will offer a read speed of 6 MB/s per mAh, which translates into a 46% improvement over to the previous generation.
When will UFS 4.0 arrive?
With the developed standard and the approval of JEDEC, Samsung will start the production of the first UFS 4.0 memories in the third quarter of this year. They will be offered to manufacturers in compact modules with a maximum dimension of 11 x 13 x 1 mm and will have a variety of capacities, with a maximum of 1 TB.
The next step will be the use of these memories by manufacturers. If we focus on the mobile world, it will surely reach the highest range devices first and as its price drops to the rest of the ranges. For now, we just have to wait.
