Non-volatile memory with selective interleaved coding based on block reliability

A method comprising:

• determining, by a controller, health scores for a plurality of blocks of a memory array, the health scores indicating the health of the blocks;
• receiving, by the controller and from a host, data having a data type;
• selecting, by the controller, an interleaving scheme for encoding the data based on the data type, wherein the interleaving scheme is one of interleaved and non-interleaved;
• and
• writing, by the controller, the data to a healthy block if a non-interleaved scheme was selected and writing the data to an unhealthy block if an interleaved scheme was selected.

An apparatus, comprising:

• a memory array;
• and
• processing means in communication with the memory array, wherein the processing means includes:
• means for determining health scores for a plurality of blocks of the memory array, the health scores indicating the health of the blocks;
• means for receiving, from a host, data having a data type;
• means for selecting an interleaving scheme for encoding the data based on the data type, wherein the interleaving scheme is one of interleaved and non-interleaved;
• and
• means for writing the data to a healthy block if a non-interleaved scheme was selected and means for writing the data to an unhealthy block if an interleaved scheme was selected.
