Universal Flash Storage Host Controller Interface (UFSHCI) Release Number: Version 4.1	JESD223F	Dec 2024
This document replaces all prior versions; however, JESD223E August 2022 (version 4.0) remains available for reference purposes. 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]. Clause 4 provides a brief overview of the architectural overview of UFS. Clause 5 describes the register interface of UFSHCI. Clause 6 describes the data structure used by UFSHCI. Clause 7 provides a theory of operation for UFSHCI. Clause 8 describes the error recovery process for UFSHCI. Committee(s): JC-64, JC-64.1 Available for purchase: $220.00 Add to Cart Paying JEDEC Members may login for free access.
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 Committee(s): JC-64.8 Available for purchase: $76.00 Add to Cart Paying JEDEC Members may login for free access.
