JEDEC updates UFS and memory interface standards

JEDEC announced the publication of JESD220G: Universal Flash Storage 4.1. In addition, an update to the complementary JESD223F UFS Host Controller Interface (UFSHCI) version 4.1 standard has also been published. Developed for mobile applications and computing systems requiring high performance with low power consumption, UFS 4.1 offers faster data access and improved performance over the earlier version of the standard while maintaining hardware compatibility to UFS 4.0. Both standards are available for download from the JEDEC website.

UFS offers high-performance, embedded storage with low power consumption, making it ideal for use in applications where power efficiency is essential. This includes computing and mobile systems like smartphones and tablets, as well as an expanding role in automotive applications and high-end IOT devices. Its high-speed serial interface and optimized protocol enable significant throughput for power-efficient system performance. UFS 4.1 and UFSHCI 4.1 together define the following improvements over prior versions of the standard:

 Host-Initiated Defragmentation: New mechanisms for optimizing read traffic through host-initiated data defragmentation facilitate more effective memory maintenance. WriteBooster Buffer Resize and Partial Flush: Allows the host to request buffer resizing, data pinning, and more granular flushing to ma...
