Abstract
A data storage device includes a memory device and a controller coupled to the memory device. The controller is configured to decode data from the memory device, store a decoder level for the decoded data in a bloom filter, receive a read command for the data, and decode the data using a decoder associated with the stored decoder level. The decoder level corresponds to a decoder having a certain decoding strength. The decoder level is stored in the bloom filter as an ID, where a bloom filter may be associated with each decoder level.
