Enhanced read performance for memory data word decoding using power allocation based on error pattern detection

A method, comprising:

• processing a plurality of data words using a first decoder engine of a decoder of a memory device according to a first power setting that is based at least in part on a first amount of power credits allocated to the decoder;
• detecting, by the decoder, a pattern of errors in the plurality of data words based at least in part on processing the plurality of data words using the first decoder engine;
• communicating, by the decoder, a status signal based at least in part on detecting the pattern of errors in the plurality of data words;
• allocating, by a resource manager based at least in part on the status signal, a second amount of power credits to the decoder;
• and
• processing, by the decoder, a portion of the plurality of data words using a second decoder engine of the decoder according to a second power setting that is based at least in part on the second amount of power credits allocated to the decoder, the second decoder engine being configured to decode data words with higher reliability than the first decoder engine.

An apparatus, comprising:

• means for processing a plurality of data words encoded using a low density parity check (LDPC) code using a first decoder engine according to a first power setting that is based at least in part on a first amount of power credits;
• means for detecting a pattern of errors in the plurality of data words based at least in part on processing the plurality of data words using the first decoder engine;
• means for allocating a second amount of power credits for decoding at least a portion of the plurality of data words based at least in part on detecting the pattern of errors in the plurality of data words;
• and
• means for processing the at least the portion of the plurality of data words using a second decoder engine according to a second power setting that is based at least in part on the second amount of power credits, the second decoder engine being configured to decode data words with higher reliability than the first decoder engine.
