Claim 4:
5. The read voltage level correction method according to claim 1, wherein the step of performing the second data read operation according to the read level tracking table and the association information recorded in the transient look-up table comprises: when the second data read operation instructs to read data of a second physical unit among the physical units, obtaining a second optimal read voltage level of the second physical unit from the read level tracking table; and
looking up the transient look-up table according to the second optimal read voltage level or an index corresponding to the second optimal read voltage level to sequentially obtain the second read voltage level corresponding to the count value as an initial read voltage level for performing the second data read operation according to a sequence of a plurality of count values from large to small.
