What is UFS 3.0: In recent days, we have been able to read several reports regarding the introduction of new smartphones, which brought a new type of memory model standard. It is worth mentioning, for example, Xiaomi Mi 10, which is proud of the memory type UFS 3.0 (editor’s note: Mi 9 has the memory type UFS 2.1). For many, this parameter does not say anything, so we decided to briefly describe its meaning.
As with computers and smartphones, the type of memory module used is important. In the case of computers, the most historically mentioned HDD disk, which is gradually being replaced by the type of SSD. Of course, these types of disks also have their own subdivisions. In essence, the same is true for smartphones.
UFS 3.0 is the latest generation of so-called Flash memory modules, UFS stands for Universal Flash Storage, which are significantly faster than eMMCs while maintaining the same power consumption values. In other words, under UFS 3.0, a memory module is hidden, which is the opposite of an SSD disk from computers. However, let’s go back to the UFS types of memory modules and to compare the current latest generation with the previous one.
UFS 3.0 vs UFS 2.0
The benefits of the new memory type standard vary. The most important, however, is the speed of reading and writing data with the same or lower power consumption. Below you can imagine the speed of downloading data or uploading to a smartphone using a cable via a computer. However, it’s not just about copying data, but also about working with data on a smartphone (eg opening applications, loading images,…).
The new UFS 3.0 standard doubles the bandwidth compared to the currently most widely used UFS 2.1 standard with a data transfer rate of 11.6 Gb / s per lane, with a maximum peak data transfer rate of 23.2 Gb / s with two lanes.
“UFS 3.0, UFSHCI 3.0, and the UFS Card Extension offer a number of enhancements over previous versions of these standards to help product designers enable significant improvements in mobile devices and related applications,” said Mian Quddus, JEDEC Chairman and Director JC-64 for built-in memory storage and removable memory cards on the occasion of the introduction of this new standard.
In addition to more than twice the speed, the new standard also brought lower operating voltage. While the previous generation worked with a voltage from 2.7 to 3.6V, the new generation works with a voltage of approximately 2.5V. In a very simplified form, this should be reflected in faster reading and writing of data combined with less energy consumption.
