Phones come with either eMMC storage or UFS (Universal Flash Storage) and it is no news that the latter is the faster type of storage. UFS used to be found mostly on flagship phones but in recent times, they have been put into mid-range devices too while eMMC storage has been relegated to entry-level devices.
The JEDEC Solid State Technology Association has now unveiled the latest version of UFS called UFS 3.1 (JESD220E). It succeeds UFS 3.0 which appeared in Samsung’s 2019 flagships and even OnePlus’s own phones too.
According to the press release by JEDEC, UFS 3.1 is designed for mobile applications and computing systems that require high-performance with low power consumption. The new storage technology brings three major improvements over the last generation. They are:
- Write Booster: an SLC non-volatile cache that amplifies write speed.
- DeepSleep: a new UFS device low power state targeting lower-cost systems that share UFS voltage regulators with other functions.
- Performance Throttling Notification: allows the UFS device to notify the host when storage performance is throttled due to high temperature.
JEDEC also announced a companion standard called UFS Host Performance Booster (HPB) Extension which provides the option to cache the UFS device logical-to-physical address map in the system’s DRAM.
There is no information regarding when we will begin to see the new storage standard in devices but we will not be surprised if it shows up first in a Samsung device.
