摘要：
A method in a memory device includes receiving data including a data block and main error correction coding (ECC) data for the data block. The data block includes a first sub-block of data and first ECC data corresponding to the first sub-block. An ECC operation is initiated to process the data block using the main ECC data. In response to the ECC operation indicating uncorrectable errors in the data, a first sub-block ECC operation is initiated to process the first sub-block of data using the first ECC data.
