Abstract
A data storage device includes a non-volatile memory and a controller coupled to the non-volatile memory. The controller is configured, based on a metric associated with a portion of the non-volatile memory, to store a read technique indicator that indicates that the portion is to be read using a high-reliability read technique.
Claims20
A data storage device comprising:
- a non-volatile memory;
- and
- a controller coupled to the non-volatile memory, the controller configured, based on a metric associated with a portion of the non-volatile memory, to store a read technique indicator that indicates that the portion is to be read using a high-reliability read technique.
A device comprising:
- a non-volatile memory;
- and
- a controller coupled to the non-volatile memory, the controller configured to receive a read command indicating a portion of the non-volatile memory and to read the portion using a high-reliability read technique in response to determining that the read command indicates that the portion is to he read using the high-reliability read technique.
A method performed by a controller, the method comprising:
- receiving a read command from an access device, the read command indicating a portion of a non-volatile memory;
- determining that a read technique indicator associated with the portion of the non-volatile memory indicates that the portion of the non-volatile memory is to be read using a high-reliability read technique;
- reading data of the portion of the non-volatile memory using the high-reliability read technique;
- and
- sending the data to the access device.
