JEDEC Published JESD220-2B Universal Flash Storage Card Extension Standard 3.0

JEDEC Solid State Technology Association published the JESD220-2B Universal Flash Storage (UFS) Card Extension Standard 3.0.

This version of the removable memory card standard defines functionality aligned with the UFS 3.0 embedded device standard already recognized in many high-end mobile and consumer-focused applications. JESD220-2B is available for download.

UFS is a performance interface designed for use in applications where power consumption needs to be minimized, including mobile systems such as smartphones and tablets as well as for automotive and IoT applications. Its fast serial interface and optimized protocol enable major improvements in throughput and system performance.

JESD220-2B UFS 3.0 card standard provides standardized platform for removable storage.

It offers following substantial improvements over prior version of flash memory standard, including:

Performance: JESD220-2B doubles the maximum interface performance to 1.2GB/s from a maximum of 600MB/s for the prior version.
Boot support: UFS Card 3.0 now offers boot support, allowing products to boot more quickly and through the use of a UFS Card.
Interoperability: To improve interoperability and sharply reduce development complexities, JESD220-2B simplifies selected features, including the removal of features not needed for the removable card such as Product State Awareness (PSA), Replay Protected Memory Block (RPMB), Context, Priority of Logical Unit, and Dynamic Capacity. UFS Card 3.0 also minimizes the number of Logical Units to simplify storage management.

Examples of potential use cases include:

Data-intensive smartphone applications
Recording data from multiple, high-resolution video cameras simultaneously (high-end drones, automotive applications)
Storage for automotive applications such as infotainment, ADAS, navigation, and black box recordings

“JEDEC’s new UFS card standard offers the same high-end functionality as the highly popular UFS embedded device standard, in a convenient card format that’s well suited for a variety of removable applications,” said Mian Quddus, chairman, board of directors, JEDEC and JC-64 committee for embedded memory storage and removable memory cards. “Supporting multiple, simultaneous data-intensive functions on a smartphone, or for use as an easily extendable storage solution within the automotive market, are just two examples of the versatility of UFS Card 3.0.”
