Summary:PURPOSE: A buffer managing method of a multiple layer flash memory and an apparatus thereof are provided to manage a buffer b using a valid data pointer and to define the valid data pointer. CONSTITUTION: A flash memory controller(20) sets up a valid data point in order for data of a sibling page not to be overlapped. When data of the sibling page is stored in the flash memory, the flash memory controller detects whether there is data damage of the sibling page. In case there is data damage of the sibling page, the flash memory controller recovers data of the sibling page in a flash memory from a buffer.
