Abstract
In an illustrative example, a data storage device includes a non-volatile memory and a controller coupled to the non-volatile memory. The controller includes an erasure correcting code engine configured to generate first erasure recovery data and temporary erasure recovery data in a volatile memory at least partially based on first data to be written to the non-volatile memory. The first erasure recovery data is configured to enable a first type of data recovery of the first data, and the temporary erasure recovery data is configured to enable a second type of data recovery of the first data. The controller is further configured to store the first erasure recovery data and the temporary erasure recovery data in the volatile memory and, after verifying that the first data is stored in the non-volatile memory, to discard or modify the temporary erasure recovery data.
