UNIVERSAL FLASH STORAGE HOST CONTROLLER INTERFACE (UFSHCI), UNIFIED MEMORY EXTENSION, Version 1.1A

JESD223-1A

Published: May 2016

This Unified Memory Extension standard is an extension to the UFSHCI standard, JESD223. The UFSHCI standard defines the interface between the UFS driver and the UFS host controller. In addition to the register interface, it defines data structures inside the system memory, which are used to exchange data, control and status information. Furthermore the UFSHCI standard defines the protocol layer structure and abstract entities within these layers. Unified Memory offers the possibility to move Device internal working memory into the system memory to reduce overall system cost and to improve Device performance. Item 203.25
