  • System and method to correct data errors using a stored count of bit values
    Patent number: 8429468
    Abstract: In a particular embodiment, at a controller coupled to a memory array, a method includes receiving an indication that a first group of data bits read from the memory array includes errors that are uncorrectable by an error correction coding (ECC) engine. A count of the first group of data bits having a particular bit value may be compared to a prior count of data bits having the particular bit value. In response to determining that the count exceeds the prior count, a bit of the first group of data bits that has the particular bit value and that corresponds to a same memory cell as a corrected data bit of a second group of data bits is identified. A value of the identified bit of the first group may be changed to generate an adjusted group of data bits. The adjusted group of data bits may be provided to the ECC engine.
