Definition

UFS 2.2 refers to version 2.2 of the UFS (Universal Flash Storage) standard. It is a non-volatile memory technology used in electronic devices, where it appears classified as a storage type or memory technology in product specification sheets.

Identification in specifications

In product specifications, UFS 2.2 is listed under categories such as storage type, storage standard, or memory technology. The designation combines the standard name (UFS) with the version number (2.2), allowing this iteration to be distinguished from other versions of the same standard.

Applications and usage context

  • It is employed as a storage technology in consumer devices, appearing in specification sheets for phones, tablets, and similar equipment.
  • It can be found in various capacities; for example, a 256 GB UFS 2.2 configuration is documented.
  • In some product configurations it is paired with LPDDR5X working memory, indicating that UFS 2.2 serves the persistent storage role while LPDDR5X acts as volatile memory.

Scope and limitations of available information

The collected evidence comes from product specification sheets and listings across several markets (Spanish, Italian, English). The consulted sources do not provide internal standard parameters (bus width, transfer speed, application-layer protocol) nor quantitative comparisons with other UFS versions. The information is limited to the identification of the standard, its version, and its presence as a storage specification in commercial products.

Interpreting its presence in a product

When a specification sheet lists UFS 2.2 as the memory or storage type, it specifies that the device uses version 2.2 of the Universal Flash Storage standard for its non-volatile storage. This designation allows the user to identify the generation of the storage technology employed and, combined with the stated capacity (e.g., 256 GB), gauge the available space for applications, files, and the operating system.

The mention of UFS 2.2 alongside LPDDR5X in the same specification reflects a typical mobile device architecture: UFS flash storage for persistent data and LPDDR memory for real-time operations.
