Claim 13:
14. The method as claimed in claim 1, wherein the performing of the first DMA read operation on the data stored in the non-volatile memory device based on the first read voltage of the history table includes:
determining whether the first read voltage is registered at the history table;
when it is determined that the first read voltage is not registered at the history table, performing a second DMA read operation based on a default read voltage;
determining whether second raw data read by the second DMA read operation include an uncorrectable error; and
when it is determined that the uncorrectable error is absent from the second raw data read by the second DMA read operation, updating the history table such that the default read voltage is set as the first read voltage.
