This document replaces all past versions, however JESD220E, January 2020 (V 3.1), is available for reference only. This standard specifies the characteristics of the UFS electrical interface and the memory device. Such characteristics include (among others) low power consumption, high data throughput, low electromagnetic interference and optimization for mass memory subsystem efficiency. The UFS electrical interface is based on an advanced differential interface by MIPI M-PHY specification which together with the MIPI UniPro specification forms the interconnect of the UFS interface.

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

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]. Item 206.25

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

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

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
