This standard defines the labels that shall be applied to all DDR5 memory modules to fully describe the key attributes of the module. The label can be in the form of a stick-on label, silk screened onto the assembly, or marked using an alternate customer-readable format. A readable point size should be used, and the number can be printed in one or more rows on the label. Hyphens may be dropped when lines are split, or when font changes sufficiently.

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.
