What is UFS 4 and why is it important for the future of smartphones

UFS 4 is the most advanced internal storage standard for smartphones and other mobile devices such as tablets, cameras, wearables, drones or handheld consoles. Approved by the organization responsible for the standard, JEDEC, manufacturers such as Samsung should start production from the third quarter of 2022.

What benefits will UFS 4 bring?

The new version of the standard, known as Universal Flash Storage, will greatly improve the performance and capacity of the current version of UFS 3.1. The goal will be to “deliver a new experience” in data-intensive tasks, high-resolution imaging, mobile gaming, 5G devices, future automotive applications, or next-generation AR and VR headsets.

UFS 4 will provide transfer rates up to 4200MB/s and 2800MB/s in sequential read/write modes. Significant improvement over 2100/1200 MB/s of current UFS 3.1. Another notable benefit is that even though it doubles the performance, it consumes 46% less power, which is important given the mobile devices that will be using it.

In addition, UFS 4 has a maximum throughput of up to 23.2Gbps per lane, which is also twice the speed of UFS 3.1, and with dual-channel support, it enables simultaneous reads and writes. This enhancement benefits 5G smartphones, in-car applications, and AR/VR-enabled devices that require high data bandwidth.

Improving storage capacity will also be important, doubling the current standard to reach the terabyte barrier, and by the way, keeping the same maximum chip size: 11 x 13 x 1mm. This would make the use of memory cards such as microSD unnecessary, although their use goes beyond 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’s safe to say that they will debut at the top of their next generation mobile phone lineup, the Galaxy S23.

Given that 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.
