• Kioxia has announced that it has begun shipping evaluation samples of UFS 5.0 embedded flash memory available in capacities of 512 GB and 1 TB. • UFS 5.0 is a new standard for embedded flash storage currently being developed by JEDEC for next-generation mobile devices. • The new standard utilizes MIPI M-PHY version 6.0 for the physical layer and UniPro version 3.0 for the protocol. • The new High-Speed Gear 6 (HS-GEAR6) mode available in M-PHY version 6.0 can handle up to 46.6 Gbps per lane, meaning that with 2 lanes, it can achieve around 10.8 GB/s read/write performance, outperforming most NVMe SSDs, except for PCIe Gen5 SSDs. • As a reminder, the previous UFS 4.0 standard promised up to 4,200 MB/s, so the upcoming UFS 5.0 standard more than doubles the theoretical speed. • Besides the higher throughput, UFS 5.0 adds the following features, according to JEDEC: - Integrated link equalization for more reliable signal integrity - Distinct power supply rail to provide noise isolation between PHY and memory subsystems, for easier system integration - Inline Hashing for greater security Kioxia says the samples incorporate an in-house newly developed controller for UFS 5.0 and the company’s 8th-generation BiCS FLASH.
