    摘要: A method includes, in a data storage device that includes a non-volatile memory, selecting an updated reference voltage as one of a reference voltage, a first alternate reference voltage and a second alternate reference voltage. The first alternate reference voltage and the second alternate reference voltage are calculated based on the reference voltage and based on a voltage increment. Selection of the updated reference voltage is based on a comparison of error counts, each error count associated with a unique one of the reference voltage, the first alternate reference voltage, and the second alternate reference voltage. The method includes resetting the reference voltage to the updated reference voltage, resetting the voltage increment to a reset voltage increment that is smaller than the voltage increment, and selecting an additional updated reference voltage based on the reset reference voltage and based on the reset voltage increment.

    摘要: A method in a data storage device 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 a second sub-block of data. The method also includes initiating an ECC operation to process the data block using the main ECC data. In response to the ECC operation indicating uncorrectable errors in the data block, first additional ECC data that is external to the data block is retrieved and a second ECC operation is initiated to process the first sub-block of data using the first additional ECC data.

    摘要: A method includes reading data from a data area of a word line and reading first ECC data from an ECC area of the word line. The method also includes, in response to determining that an error indicator exceeds a threshold, storing second ECC data in the ECC area. The second ECC data corresponds to a subsection of the data area.

    摘要: A method includes initiating a first decode operation of data at an error correction code (ECC) hard bit decoder in a data storage device that includes a controller and a memory. The method further includes, in response to the first decode operation indicating that the data is uncorrectable by the first decode operation, identifying one or more bits of the data that correspond to a disturb condition test pattern, changing a value of the one or more identified bits of the data to generate modified data, and initiating a second decode operation at the ECC hard bit decoder using the modified data.
