    reading one of a plurality of records, which corresponds to the flash ID, from a non-volatile memory, wherein each record comprises a plurality of retry parameters; and

    generating the retry-read microcodes according to the retry parameters; and

    after a successful boot, receiving a retry-read command from a host device through a first access interface; and

    starting a state machine to execute the microcodes of the retry-read operation of the instruction buffer.
