UNIVERSAL FLASH STORAGE HOST CONTROLLER INTERFACE (UFSHCI), UNIFIED MEMORY EXTENSION, Version 1.1A

 JESD223-1B May 2016

This Unified Memory Extension standard is an extension to the UFSHCI standard, JESD223. The UFSHCI standard defines the interface between the UFS driver and the UFS host controller. In addition to the register interface, it defines data structures inside the system memory, which are used to exchange data, control and status information. Furthermore the UFSHCI standard defines the protocol layer structure and abstract entities within these layers. Unified Memory offers the possibility to move Device internal working memory into the system memory to reduce overall system cost and to improve Device performance. Item 203.25

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.

UNIVERSAL FLASH STORAGE (UFS) UNIFIED MEMORY EXTENSION, Version 1.1

 JESD220-1A Mar 2016

This UFS Unified Memory Support Extension standard is an extension to the UFS standard, JESD220, This standard defines a managed storage device. UFS devices are designed to offer a high performance with low power consumption. The UFS device contains features that support both high throughput for large data transfers and performance for small random data accesses. This standard describes the requirements to implement unified memory functionality in an UFS device. Unified Memory Support is not mandatory but optional. Item 133.11

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

 JESD88F Feb 2018

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 (UFS) TEST

 JESD224A Jul 2017

JESD224A is valid only for UFS 2.1 and should not be referenced for other versions of the UFS standard.

The primary objective of this test standard is to specify the test cases for UFS device protocol conformance testing. This test standard provides test cases for checking the functions defined in the following target standard: JESD220. Universal Flash Storage (UFS) Standard version 1.1A. MIPI M-PHY and MIPI UniPro test cases are not in the scope of this document. Item 400.36

Part Model Electrical Guidelines for Electronic-Device Packages – XML Requirements

 JEP30-E100G Feb 2025

This standard establishes the requirements for exchanging part data between part manufacturers and their customers for electrical and electronic products. This standard applies to all forms of electronic parts. It forms part of the Part Model XML Schema, which covers the parental structure for the electrical, physical, Electrical, assembly process classification data along with materials and substances that may be present in the supplied product or subproducts. This Guideline specifically focuses on the “Electrical” sub-section of the Part Model.
