Kioxia officially announced that UFS 5.0 flash memory has been sampled and will continue to introduce new flash memory technology into UFS products to meet the growing demand for larger capacity and higher performance in the mobile market, enabling smartphones and other devices to implement high-performance in-device AI functions.
The samples sent by Kioxia for testing this time use its own developed main control, provide 512GB and 1TB capacities, support BiCS8 FLASH technology, and are packaged in a small size of 7.5 x 13 mm, which improves space efficiency and design flexibility.
Among them, 512GB samples are being sent to customers, and 1TB samples are scheduled to be sent next month to allow customers developing UFS 5.0-compatible systems to conduct performance evaluation and interoperability testing.
At present, the JEDEC Solid State Technology Association has not officially released the UFS 5.0 standard, which is still being formulated to meet the performance needs of the next generation of mobile devices. It uses MIPI M-PHY v6.0 as the physical layer and introduces the new HS-GEAR6 mode. In addition, the UniPro v3.0 specification is used as the protocol to build the foundation of the interconnection layer.
Theoretically, UFS 5.0 supports an interface rate of up to 46.6Gbps per channel. With dual channels, it can achieve an effective read and write performance of 10.8 GB/s, which is more than twice that of the previous generation UFS 4.0 (4.2GB/s).
In terms of security functions, UFS 5.0 also adds an inline hash function, which allows the storage module to perform instant hash calculations during the reading and writing process, reducing the risk of unauthorized access and tampering.
