Abstract
A method for performing memory access of a Flash cell of a Flash memory includes: performing a first sensing operation corresponding to a first sensing voltage to generate a first digital value of the Flash cell; according to a result of the first sensing operation, performing a plurality of second sensing operations to generate a second digital value of the Flash cell representing at least one candidate threshold voltage of the Flash cell; determining the threshold voltage of the memory Flash cell according to the at least one candidate threshold voltage; determining soft information of a bit stored in the Flash cell according to the threshold voltage of the Flash cell; and using the soft information to perform soft decoding.
