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.

This publication examines the LTS requirements of wafers, dice, and packaged solid-state devices. The user should evaluate and choose the best practices to ensure their product will maintain as-received device integrity and minimize age- and storage-related degradation effects.

Editorial, Terminology Update. This standard defines the dc and ac single-ended (data) and differential (clock) operating conditions, I/O impedance's, and the termination and calibration scheme for 1.35 V Pseudo Open Drain I/Os. The 1.35 V Pseudo Open Drain interface, also known as POD135, is primarily used to communicate with GDDR5 or GDDR5M SGRAM devices. Item 146.01B

This document describes the serial presence detect (SPD) values for all DDR5 memory modules. In this context, “modules” applies to memory modules like traditional Dual In-line Memory Modules (DIMMs) or solder-down motherboard applications. The SPD data provides critical information about all modules on the memory channel and is intended to be use by the system's BIOS in order to properly initialize and optimize the system memory channels. Item 2260.01M

Terminology Update, see Annex. This standard defines JEDEC requirements for solid state drives. For each defined class of solid state drive, the standard defines the conditions of use and the corresponding endurance verification requirements. Although endurance is to be rated based upon the standard conditions of use for the class, the standard also sets out requirements for possible additional use conditions as agreed to between manufacturer and purchaser.  Revision A includes further information on SSD Capacity.

The JEDEC Board of Directors is responsible for establishing appropriate committees to conduct its standardization activities. These committees are assigned either service or product responsibilities. It is a primary function of each committee to propose JEDEC Standards and to formulate policies, procedures, formats, and other documents that are then submitted to the Board of Directors for action or approval. This publication identifies the service and product committees established by the Board of Directors and defines their scopes.

The manufacturers identification code is defined by one or more 8 bit fields, each consisting of 7 data bits plus 1 odd parity bit. The manufacturers identification code is assigned, maintained and updated by the JEDEC Office. The intent of this identification code is that it may be used whenever a digital field is required, e.g., hardware, software, documentation, etc. To make a request for an ID Code please go to http://www.jedec.org/Home/MIDCODE_request.cfm
