Abstract
An exemplary embodiment of the invention provides a read voltage control method for a rewritable non-volatile memory module. The method includes: sending a first read command sequence which instructs a reading of a plurality of first memory cells by using a first voltage level to obtain first data; obtaining first adjustment information of a read voltage according to the first data and a channel parameter of the first memory cells, and the channel parameter reflects a channel status of the first memory cells; and adjusting a voltage level of the read voltage from the first voltage level to a second voltage level according to the first adjustment information.
