Abstract
A Flash memory access module performs memory access management of a Flash storage device including a plurality of storage cells. The Flash memory access module includes: a read only memory for storing a program code; and a microprocessor which executes the program code to perform the following steps: performing a first sensing operation corresponding to a first sensing voltage in a storage cell, and performing a second sensing operation in the storage cell; using the first sensing operation and at least the second sensing operation to generate a first digital value and a second digital value, respectively, of the storage cell; using the first digital value and the second digital value to obtain soft information of a same bit stored in the storage cell; and using the soft information to perform soft decoding.
