UNIVERSAL FLASH STORAGE, Version 4.0	JESD220F	Aug 2022
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.

RECOMMENDED ESD-CDM TARGET LEVELS	JEP157A	Apr 2022
This document was written with the intent to provide information for quality organizations in both semiconductor companies and their customers to assess and make decisions on safe ESD CDM level requirements. Committee(s): JC-14, JC-14.3 Free download. Registration or login required.
SYSTEM LEVEL ESD: PART II: IMPLEMENTATION OF EFFECTIVE ESD ROBUST DESIGNS This is an editorial revision, details can be found in Annex F.	JEP162A.01	Jan 2021
This document, while establishing the complex nature of System Level ESD, proposes that an efficient ESD design can only be achieved when the interaction of the various components under ESD conditions are analyzed at the system level. This objective requires an appropriate characterization of the components and a methodology to assess the entire system using simulation data. This is applicable to system failures of different categories (such as hard, soft, and electromagnetic interference (EMI)). This type of systematic approach is long overdue and represents an advanced design approach which replaces the misconception, as discussed in detail in JEP161, that a system will be sufficiently robust if all components exceed a certain ESD level.

UNIVERSAL FLASH STORAGE, UFS 2.2	JESD220C-2.2	Aug 2020
The purpose of this standard is definition of a UFS Universal Flash Storage electrical interface and a UFS memory device. This standard defines a unique UFS feature set and includes the feature set of eMMC standard as a subset. This standard replaces JESD220C, UFS 2.1, and introduces a feature called WriteBooster. Item 138.88. Committee(s): JC-64.1 Free download. Registration or login required.
UNIVERSAL FLASH STORAGE (UFS), Version 3.1	JESD220E	Jan 2020
This document has been superseded by JESD220F, August 2022, however is available for reference only.
