Abstract: The present disclosure relates to data error correction methods and apparatuses. One example method is applied to to-be-corrected data in a storage medium. Column check information is set for the to-be-corrected data, and the column check information includes check data of each column of data in the to-be-corrected data. The example method includes determining that first-row data in to-be-corrected data includes an uncorrected error, and performing error correction on each column of data in the to-be-corrected data based on column check information of the to-be-corrected data, where each column of data includes one bit of data in the first-row data. For each bit of data in the first-row data, if the bit of data is incorrect, after error correction is performed on a column in which the bit of data is located, the bit of data is corrected.
