  • Enhanced error correction in memory devices
    Patent number: 8996936
    Abstract: A method of correcting stored data includes reading data stored in a portion of a nonvolatile memory. The method includes, for each particular bit position of the read data, updating a count of data error instances associated with the particular bit position in response to detecting that the read data differs from a corresponding reference value of the particular bit position. The reading of the first portion and the updating of the counts of data error instances are performed for a particular number of repetitions. The method includes identifying each bit position having an associated count of data error instances equal to the particular number of repetitions as a recurring error bit position.
