Abstract
Systems, methods, and other embodiments associated with decoder based data recovery are described. According to one embodiment, an apparatus includes a decoder configured to decode codewords and decoder firmware configured to control one or more decoding parameters of the decoder. The decoder includes a recovery unit configured to store recovery instructions. The decoder is further configured to execute the stored recovery instructions without interaction with the decoder firmware when the decoding fails.
Claims20
An apparatus, comprising:
- a decoder configured to decode codewords;
- decoder firmware configured to control one or more decoding parameters of the decoder;
- and
- wherein the decoder comprises a recovery unit configured to store recovery instructions, wherein the decoder is further configured to execute the stored recovery instructions without interaction with the decoder firmware when the decoding fails.
1 more element
A method, comprising, with a decoder:
- decoding a codeword;
- detecting a decoding failure;
- executing, without interaction with computing components external to the decoder, recovery instructions stored in the decoder;
- and
- returning results of the execution of the recovery instructions.
2 more elements
A device comprising:
- a memory device configured to store data encoded as codewords;
- a decoder configured to decode codewords retrieved from the memory device;
- and decoder firmware configured to control one or more decoding parameters of the decoder;
- wherein the decoder comprises a recovery unit configured to store recovery instructions and further wherein the decoder is configured to, when the decoder fails to decode a codeword, execute the stored recovery instructions without interaction with the decoder firmware while the memory device prepares to re-read the codeword.
