NON-VOLATILE MEMORY SYSTEM AND MANAGEMENT METHOD THEREFOR

摘要

PURPOSE: A non-volatile memory system and a managing method thereof are provided to record data without a merging operation to a buffer block when a log block is not allocated to a data block. CONSTITUTION: A memory area(150) includes non-volatile blocks. A MCU(Micro Control Unit)(130) manages the memory block with a data block and a buffer block. If the buffer block allocated to the data block does not exist and a pre-page exists in the data block, the MCU replaces the data block with a self-buffer block. The MCU stores an address mapping table and updates it according to replacement of the data block with the self-buffer block.
