Abstract
A method for performing memory access includes: performing a plurality of sensing operations respectively corresponding to a plurality of different sensing voltages to generate a first digital value of a Flash cell of a Flash memory and a second digital value of the Flash cell of the Flash memory; using the first digital value and the second digital value to obtain soft information of a bit stored in the Flash cell; and using the soft information to perform soft decoding.
Claims15
