UFS 3.0 specification now finalized for the next generation of smartphones and automobiles
JEDEC, the association for the development of solid-state technology standards, has made public the core specifications for the next version of its Universal Flash Storage standard. Called UFS 3.0, the announcement comes almost 5 years after the introduction of UFS 2.0 with performance benefits of up to 2x over the old specification.
The refreshed spec sheet is still limited to two lanes like UFS 2.0 and UFS 2.1, but each lane will now be capable of transferring 11.6 Gbps compared to 5.8 Gbps for UFS 2.0 for a maximum theoretical bandwidth of 2900 MB/s. Aside from the expected performance benefits, UFS 3.0 will also improve upon the lifespan of NAND cells and provide up to 2.5 V of electricity in order to support forthcoming NAND technologies.
Currently, many flagship Android smartphones utilize UFS including the Nubia Z17, Huawei Mate 9, Sony Xperia XZ, and countless others. JEDEC is looking to expand the application of UFS onto automobiles by extending its operating range to encompass temperatures as low as -40 C up to 105 C with adjustments to the host controller for improved reliability. Cars with high capacity NAND flash may seem frivolous at the moment, but the institution is likely seeing a lucrative market with the advent of tech-driven self-driving cars.
No smartphones have been announced with UFS 3.0 technology at the time of writing. Nonetheless, this could soon change with MWC 2018 just around the corner where prototype smartphones are often on display.
