ABSTRACT:
A voltage regulating method applied to a memory to regulate a word line voltage corresponding to a set of memory cells of the memory includes the following steps. Firstly, a first value, which is for indicating an amount of data having a specific data value in a set of written data, is counted, wherein the set of written data is written into the set of memory cells. Next, a second value, which is for indicating an amount of data having the specific data value in a set of read data, is counted, wherein the set of read data is obtained by reading the set of written data. Then, a regulating voltage is determined according to a difference between the first and second values. After that, the word line voltage is regulated to be a sum of the word line voltage and the regulating voltage.
