Abstract
The present disclosure generally relates to utilizing a transparent host memory buffer (HMB) where the host device is granted access to the HMB to obtain data from a mapping table. The data storage device stores the mapping table in HMB and then allows the host device to view the mapping table and retrieve information. The host device sends a command to the data storage device that includes not only a read command, but also mapping table info specific to the read command. Additionally, an indication of the mapping table version from where the information is also provided. The data storage device, upon receiving the command, confirms the version of the information is the most recent version and then, if confirmed, utilizes the mapping information provided with the command. In so doing, accessing the HMB after receiving the command will not be necessary.
