Abstract
When entering low power mode, any commands that are fetched and waiting to be executed are completed. When the data storage device exits low power mode, new commands are fetched. The completing and fetching takes time. Rather than completing all of the commands, some selected commands can be stored in a persistent memory region (PMR) when entering low power mode. The storing in PMR is faster than completing the commands. Furthermore, retrieving the commands from PMR is faster than retrieving new commands from a host device on exiting low power mode. Thus, using PMR results in more efficient use of data storage device bandwidth.
