What is a UFS memory chip? What is UFS 3.0, UFS 3.1? Does iPhone use UFS?

You may have heard about UFS memory chips as well as UFS 3.0, UFS 3.1 on technology forums in the past days when Vivo iQOO 3 phone was just launched. The following article will help you learn more about this concept.

What is a UFS memory chip?

UFS (short for Universal Flash Storage) is a storage standard commonly used on many electronic devices today, developed by JEDEC Solid State Technology Association .

UFS memory chip has the advantage of transferring data at high speed thanks to parallel data streams, capable of both reading and writing at the same time . Compared to the previous generation eMMC memory chip standard, which can only read or write at a time, UFS memory chips help improve data access speed significantly with only almost the same power consumption as eMMC.

Currently, UFS memory chips are often preferred for devices equipped with high-end processors such as Snapdragon 865, … to help make the most of the memory’s data recording capacity.

What is UFS 3.0, UFS 3.1?

The first UFS memory chip standard was introduced in 2011, then upgraded through versions UFS 2.0, UFS 2.1 and in 2018, the UFS 3.0 standard was officially released.

Therefore, it can be understood that UFS 3.0 is essentially version 3.0 of UFS memory chips. Currently, Samsung is the world’s leading supplier of UFS memory chips.

UFS 3.1 is an upgrade of UFS 3.0 launched in early 2020, equipped by Vivo brand in its iQOO 3 phone to help deliver outstanding data recording performance while also effectively saving energy.

Speed of UFS

The recording speed of UFS memory chip is much faster than that of phones in the same segment using eMMC memory chips, and is likened to an SSD version compared to HDD on a computer.

Even so, the first generation UFS is not widely used because the speed difference is not much with eMMC. However, after being developed to UFS 2.0, the read / write speed of the chip is significantly increased, until the latest version 3.1, this speed has reached 2100 / 1200 MB / s , equivalent to a drive cheap PCIe NVMe SSD disk but with lower random read speed (about 100,000 IOPS ).

Does iPhone use UFS?

In 2015, the UFS memory chip was not widely used and its writing speed was not really outstanding. Therefore, at this time, Apple released the iPhone 6s and decided not to change from eMMC memory chip to UFS, but instead use NVMe memory.

At that time, Apple redesigned the NVMe controller to suit the phone version, and combined with the TLC NAND memory chip to help the iPhone 6s outperform all other competitors at the same time, even after when the UFS 2.1 memory chip was released in 2016.

However, the current speed of UFS 3.0 and the latest 3.1 has almost surpassed Apple’s NVMe. Although this speed depends a lot on the CPU, RAM, … but the memory chip speed is still a decisive factor to the device’s ability to read and copy data.

The article has helped you define UFS memory chips, as well as the new generation UFS 3.0, UFS 3.1. Hope this information is useful to you.
