Abstract

Techniques for performing background refresh for storage devices using a timestamp from the host are described. In one example, a method involves receiving a timestamp from a host, storing the timestamp in a storage device, and determining a retention time for data stored in one or more blocks of the storage device based on the timestamp relative to a second timestamp indicating when the data was written to the one or more blocks. In response to determining the retention time exceeds a threshold, the storage device moves the data to one or more other blocks of the storage device, which can include interleaving the refresh writes with activity from the host.
