US Patent 11954367 Active time-based command prioritization in data storage devices

Disclosed are systems and methods providing active time-based prioritization in host-managed stream devices. The method includes receiving a plurality of host commands from a host system. The method also includes computing active times of open memory regions. The method also includes determining one or more regions that have remained open for more than a threshold time period, based on the active times. The method also includes prioritizing one or more host commands from amongst the plurality of host commands for completion, the one or more host commands having corresponding logical addresses belonging to the one or more regions, thereby (i) minimizing risk to data and (ii) releasing resources corresponding to the one or more regions.
