What is UFS 4.0 and how will it change smartphones



there JEDEC Solid State Technology Association (the body that defines and approves solid-state storage memory standards), announced the approval of specifications related to the new standard UFS 4.0. The new standard for storage memories This will improve the performance of high-end smartphones, for which they will be able to get more 1 terabyte Space for photos, videos, music, and apps.

What changes with UFS 4.0

The first manufacturer to actually announce the first memories of UFS 4.0 were Samsung. The Korean giant talks about a transfer speed of up to 4200 megabytes per second (MB/sec) for sequential read and up to 2800 MB/s write.

A big step forward if you think typing speed is standard UFS 3.1 from 2020 (now used at the top of the range) is 1200MB/s, while that UFS 3.0 As of 2018, the limit is only 410MB/s.

At the same time, theEnergy efficiency It is further improved. The memory supply voltage has been reduced from 3.3V to 2.5V Thus consumption should fall by 46%. All in favor of mobile battery life with UFS 4.0 storage.

Samsung claims UFS 4.0 offers up to 23.2 Gbps per lane, double the bandwidth compared to the current UFS 3.1 standard. The higher bandwidth is ideal for 5G smartphones, as massive amounts of data need to be processed quickly.

Space up to 8 terabytes

The new standard is Backwards compatible with UFS 3.1 and 3.0 standards, which will make it possible to maintain a common architecture. The new UFS 4.0 memory, according to Samsung’s announcement, will have dimensions 11 x 13 x 1 mm in version of 1 terabyte. This means that integration will be possible Huge amounts of ultra-fast UFS 4.0 storage in very small spaces 2And the 4 or even 8 TB of storage in a smart phone.

Production of the new UFS 4.0 chips has already begun, and the first devices with the new memory should arrive this year or early next year at the latest. Samsung may already be using it on its upcoming smartphones in the series Galaxy S23.

Other manufacturers like OnePlus, Vivo, and iQOO will be buying the new memories from Samsung to install on their upcoming flagships. Vivo X90 Pro +which was just introduced in China, uses UFS 4.0 memories for example.
