Abstract:
1. A method of reading data stored in a non-volatile memory array of a memory system, comprising: reading an ECC (error correction code) code word written in memory cells along a word line of the non-volatile memory array, the ECC code word including a plurality of bits of data and one or more bits of error correction code associated with the data; identifying an area along the word line from which the ECC code word was read that indicates a cluster of errors; altering the value of one or more bits of the ECC code word as read from the identified area; feeding the ECC code word with the altered values to ECC circuitry on the memory system; and determining by the ECC circuitry of whether the ECC code word with the altered values is successfully decoded by the ECC circuitry.
