JEDEC Solid State Technology Association, the global leader in the development of standards for the microelectronics industry, today announced the publication of key updates to its Universal Flash Storage (UFS) standard. Specifically tailored for mobile applications and computing systems requiring high performance and low power consumption, the new UFS v1.1 standard is an update to the v1.0 standard published in 2011, incorporating feedback from industry UFS technology implementers. JESD220A Universal Flash Storage v1.1 contains important amendments and references to the latest related MIPI Alliance specifications, and may be downloaded free of charge from the JEDEC website here.

JEDEC has also published a complementary standard, JESD223A UFS Host Controller Interface (HCI) v1.1. JESD223A defines a standard host controller interface on which system designers can create a common host controller software driver layer to work with UFS host controller hardware from different manufacturers. The HCI functionality also enables higher performance and power efficiency by minimizing the involvement of the host processor in the operation of the Flash storage subsystem. JESD223A Universal Flash Storage Host Controller Interface v1.1 may also be downloaded free of charge here.
