Samsung recently made a big news, upgrading the universal flash memory from UFS 3.1 to UFS 4.0. This is not yet Samsung Show Muscle, UFS 4.0 has been approved by JEDEC (Solid State Technology Association) and plans to start mass production in the third quarter of this year.
Does this have anything to do with the parameter party we play with the machine?
Of course. We often say that flagship phones have a performance triangle, Snapdragon 8 chip + LPDDR5 memory + UFS 3.1 flash memory. Now, the Iron Triangle is about to be replaced, and we will see mobile phones equipped with UFS 4.0 flash memory as early as the second half of this year.
By the time the next generation of Snapdragon chips are released next year, the new performance triangle of the flagship machine will be a combination of Snapdragon 8 Gen2 chips + LPDDR5 memory + UFS 4.0 flash memory.
Now many users find that the 2,000 yuan mobile phone and the 4,000 yuan mobile phone, there is not much difference in performance. In addition to the price, the flagship machine has not been able to "flagship" many times. I believe that by next year, the real performance replacement of the flagship machine will come.
Where is the Samsung UFS 4.0?
First, the UFS 4.0 has a speed of up to 23.2Gbps per channel, twice as fast as Samsung's predecessor, the UFS 3.1. According to Samsung, "such a large bandwidth is ideal for 5G smartphones that require a lot of data processing."
UFS 3.1 flash memory has a maximum read rate of 2100MB/s and a maximum write rate of 1200MB/s. The UFS 4.0 flash memory has a maximum read rate of 4200MB/s and a maximum write rate of 2800MB/s. From UFS 3.0 to UFS 3.1, there is no major change in the maximum reading speed, and this upgrade to UFS4.0 directly doubles the speed.
Secondly, the energy efficiency of UFS 4.0 has also been improved. UFS 4.0 has a sequential read speed of 6.0MB/s per mAh, which is 46% higher than the previous generation. As a result, users can transfer more data while consuming the same amount of power.
Finally, the UFS 4.0 flash memory chip has a package size of only 11x13x1mm, and the maximum capacity can reach 1TB. While the size is smaller than the previous generation, the maximum capacity is larger. I believe that in the near future, the SD card slot on Android phones may be disappearing.
What is UFS Flash?
Take the 8GB+128GB specification of the mobile phone we often say as an example, 8GB refers to the memory, and the flash memory refers to the 128GB part, which is the size of the mobile phone storage space that we usually say.
There are many standards for flash memory, and UFS is the latest standard, which first appeared in 2011. Since 2016, UFS flash memory has been widely used in mobile phones. The reason why it is 2016 is because qualcomm released the Snapdragon 835 chip this year began to support UFS2.1.
Now it seems that the mobile phone that can first carry UFS 4.0 is likely to be a new generation of Samsung's products, such as the folding screen Samsung Galaxy Z Fold 4 in the second half of the year, or the digital flagship Samsung Galaxy S23 next year.
