UFS 4 is the most advanced standard for internal storage of smartphones and other mobile devices, such as tablets, cameras, wearable devices, drones or portable consoles. Manufacturers such as Samsung are expected to begin production in the third quarter of 2022, after approval by the organization responsible for the JEDEC standard.
What are the benefits of UFS 4?
The new version of the standard known as universal-flash-storage will significantly improve the performance and capacity of the current version of UFS 3.1. The goal will be “Provide new experience” for tasks that require large amounts of data processing, high-resolution images, mobile games, 5G devices, future automotive applications, or next-generation AR and VR headsets.
UFS 4 offers data rates up to 4,200 MB / s and 2,800 MB / s in sequential read / write mode. Significant improvement over 2,100 / 1,200 MB / s current UFS 3.1. Another significant advantage is that even though it doubles the power, it consumes 46% less energy, which is important with regard to the mobile devices that will use it.
In addition, UFS 4 has a maximum bandwidth of up to 23.2 Gbps per lane, which is also twice the speed of UFS 3.1, andWith bidirectional transfer support, it allows simultaneous read and write operations. This enhancement brings benefits to 5G smartphones, automotive applications and AR / VR-enabled devices that require high data throughput.
It will also be important improved storage capacity, doubling the current standard to achieve the Tbyte barrier, and by the way maintaining the same maximum chip size: 11 x 13 x 1 mm. This would make it unnecessary to use memory cards such as microSD, even if their use exceeds storage.
Which devices will release UFS 4
Samsung has announced that it will begin mass production of chips according to this standard in the third quarter of 2022, so it is certain that it will place them at the top of its next-generation mobile phones, the so-called Galaxy S23.

As Samsung is also a global semiconductor supplier and sells chips to all manufacturers, Xiaomi, Huawei, Google, Oppo and others are likely to adopt this next-generation storage standard in 2023.
