SOLID STATE DRIVE (SSD) REQUIREMENTS AND ENDURANCE TEST METHOD

 JESD218B.03 Aug 2024

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. Items 303.19, 303.20, 303.21, 303.22, 303.23, 303.26, 303.27, 303.28, and 303.32

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.

Universal Flash Storage Host Controller Interface (UFSHCI), Version 4.0

 JESD223E Aug 2022

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
