Abstract
An erased block reverification method for a solid state storage device is provided. Firstly, an erase command corresponding to a selected block is issued to an array control circuit. When an erase pass message is received, a judging step is performed to judge whether a setting condition of the selected block is satisfied. If the setting condition of the selected block is satisfied, the selected block is recorded as a good block. If the setting condition of the selected block is not satisfied, a selected block reverification process is performed. During the selected block reverification process, a data of the selected block is read and the selected block is recorded as the good block or a defective block according to a number of memory cells of the selected block in a non-erase state.
