UFS 4.0 protocol officially announced: high bandwidth, low power consumption, more security, related products will come out at the end of the year as soon as possible



Thank you IT home netizens OC_Formula The clue is delivered!

IT House August 18 news, today, the JEDEC Solid State Technology Association officially released the UFS 4.0 protocol.

Developed for mobile applications and computing systems to meet the demands of high performance and low power consumption, UFS 4.0 introduces significant bandwidth and data protection improvements over earlier versions of the standard, resulting in higher bandwidth, lower Power consumption, more comprehensive security! Help mobile storage accelerate!

In addition, JEDEC also released the UFSHCI 4.0 (JESD223E) supplementary protocol, and the new UFS 3.1 supporting standard JESD231, which is optimized on the previous basis. Relevant finished products will come out at the end of this year as soon as possible, let us wait and see.

UFS is a high-performance protocol mainly used in computing and mobile systems such as smartphones and tablets, so low power consumption is the main requirement. With high-speed serial interfaces and optimized protocols, it achieves significant increases in throughput and mobile system performance.

Together, UFS 4.0 and UFSHCI 4.0 define the following improvements over previous versions of the standard:

  • For the highest performance and most power efficient data transfer, JEDEC UFS utilizes the MIPI Alliance’s industry-leading specifications to form its interconnect layer. UFS 4.0 utilizes the M-PHY 5.0 specification and the UniPro 2.0 specification, ultimately doubling the bandwidth of the UFS interface, with read and write traffic up to 4.2GB/s.

  • Introduced multi-circular queue definition to meet more storage I/O pattern requirements

  • Introduced a more advanced RMPB interface to increase bandwidth and protect data security

In addition, UFS 4.0 offers several enhancements designed to improve the overall performance of the device, energy efficiency and ease of integration with future cutting-edge solutions:

  • A more efficient VCC=2.5V is used instead of the 3.3V in previous versions of the standard

  • Improved system latency by enabling high-speed link startup, out-of-order data transfers, and BARRIER commands

  • System integration is simplified by introducing enhanced device error history with host configurable timestamps and M-PHY’s eye monitor.

  • Retains backward compatibility with UFS 3.1 and 3.0, allowing mixed system applications

  • Finally, as an optional extension to UFS 3.1 and above, the new file-based optimization JESD231 standard allows hosts to accelerate read traffic based on host-provided file system information.

At the industry application level, Yihua, Kioxia, Samsung Electronics, Micron, and Synopsys have all provided support.
