Original Abstract Submitted

In one embodiment, a data storage device is provided comprising a memory and a controller. The controller is configured to: receive, from a host, a command to read data from the memory, wherein the command comprises a data integrity level threshold; read the data from the memory; determine a data integrity level of the data; in response to the data integrity level of the data being above the threshold, send the data to the host; and in response to the data integrity level of the data not being above the threshold: perform at least one iteration of an error correction operation on the data until the data integrity level of the data is above the threshold; and send the data to the host. Other embodiments are provided, and each of the embodiments can be used alone or in combination.
