This standard defines the DDR5 SDRAM Specification, including features, functionalities, AC and DC characteristics, packages, and ball/signal assignments. The purpose of this Standard is to define the minimum set of requirements for JEDEC compliant 8 Gb through 32 Gb for x4, x8, and x16 DDR5 SDRAM devices. This standard was created based on the DDR4 standards (JESD79-4) and some aspects of the DDR, DDR2, DDR3, and LPDDR4 standards (JESD79, JESD79-2, JESD79-3, and JESD209-4). Item 1848.99M.

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 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.

In some cases, JEDEC Committees have established additional policies and guidelines to facilitate the operation of a particular committee. Additional policies and guidelines are set forth here as an addendum to JM21 to facilitate the operation of particular committees. These policies are in addition to the requirements set forth in JM21 and in no case shall these additions contradict or supersede the requirements in JM21.
