More Information
Summary:A data accessing method, a memory controlling circuit unit and a memory storage device are provided. The method includes: reading a first physical programming unit by using a first read voltage to obtain first data; reading the first physical programming unit by using a second read voltage to obtain second data; inputting a first state parameter corresponding to the first data and a second state parameter corresponding to the second data into an numerical calculation engine, and the numerical calculation engine determines a third reading voltage for reading the first physical programming unit.
