DICTIONARY OF TERMS FOR SOLID-STATE TECHNOLOGY, 7th Edition

 JESD88G Mar 2025

This reference for technical writers and educators, manufacturers, and buyers and users of discrete solid state devices is now available. It should aid the technical committees of JEDEC in the avoidance of multiple definitions and reduce the proliferation of redundant definitions. The long-term goal is to include definitions from all JEDEC publications and standards. Each of the approximately two thousand entries is referenced to its source publication, and an annex listing the names of the source publications and their releases dates is included. All entries were reviewed for punctuation, grammar, and clarity, as well as accuracy, and reworded if such was considered warranted. The purpose of this dictionary is to promote the uniform use of terms, definitions, abbreviations, and symbols throughout the solid state industry

Universal Flash Storage Host Controller Interface (UFSHCI)

Release Number: Version 4.1 		JESD223F Dec 2024

This document replaces all prior versions; however, JESD223E August 2022 (version 4.0) remains available for reference purposes.

This standard describes a functional specification of the Host Controller Interface (HCI) for Universal Flash Storage (UFS). The objective of UFSHCI is to provide a uniform interface method of accessing the UFS hardware capabilities so that a standard/common Driver can be provided for the Host Controller. The common Driver would work with UFS host controller from any vendor. This standard includes a description of the hardware/software interface between system software and the host controller hardware. It is intended for hardware designers, system builders and software developers. This standard is a companion document to [UFS], Universal Flash Storage (UFS). The reader is assumed to be familiar with [UFS], [MIPI-UNIPRO], and [MIPI-M-PHY].

Clause 4 provides a brief overview of the architectural overview of UFS. Clause 5 describes the register interface of UFSHCI. Clause 6 describes the data structure used by UFSHCI. Clause 7 provides a theory of operation for UFSHCI. Clause 8 describes the error recovery process for UFSHCI.
