More Information
Summary:A data storing method, a memory control circuit unit, and a memory storage apparatus are provided. The method includes recording a bit error count of every predetermined area of every physical erasing unit and determining whether the bit error count of one of the predetermined areas of the physical programming unit of the physical erasing unit is more than a threshold bit error count. If the bit error count of one of the predetermined areas of the physical programming unit of the physical erasing unit is more than the threshold bit error count, the method also includes storing data under a second programming mode after an erasing operation is performed on the physical easing unit. Accordingly, defective physical erasing units may be effectively employed to prolong the lifespan of the memory storage apparatus.
