Abstract
A data processing method for a solid state storage device is provided. The solid state storage device includes a non-volatile memory having a least one data segment. The data segment includes multiple memory cells. The data processing method includes the following steps. Whether a data stored in the data segment is an invalid data is determined according to a predetermined condition. A voltage is applied to the data segment to obtain a number of the conducted memory cells under the voltage. The voltage corresponds to a preset value. Whether the data is the invalid data is determined by judging whether a relationship between the number of the conducted memory cells and the preset value satisfies the predetermined condition.
