The JEDEC Solid State Technology Association has officially introduced the new UFS 2.2 flash memory standard, the highlight of which is the Write Booster technology, which can significantly increase write speed. The agency provided an exhaustive list of UFS 2.2 features and spoke about key improvements over its predecessor.

One of the main features of UFS 2.2 is support for the Write Booster function, which literally translates as “write accelerator”. Compared to the 2.1 specification, UFS 2.2 has significantly increased the write speed to memory: this leads to a reduction in the time required for launching applications and loading the cache.

Compared to the outdated eMMC standard, which is still found in budget mobile devices, UFS 2.2 provides synchronous writing and reading, since it supports multiple commands at the hardware level. Also, the read / write speed of UFS is higher than that of eMMC, since JEDEC took care of the use of high-density NAND memory and the close interconnection of the device chip with the memory.

In comparison, UFS 2.1 can deliver 750Mbps sequential read speeds, while eMMC 5.1 is only 282Mbps. UFS sequential write speeds also outperform eMMC by 30%. In the case of UFS 2.2, this gap will be even wider.

The first mobile platforms to receive support for the UFS 2.2 memory standard were the mid-budget MediaTek Dimensity 800U and Dimensity 720.
