Method for managing non-volatile memory, and memory-based apparatus including the non-volatile memory

The administration method of the non-volatile memory and non-volatile memory based devices are disclosed. Non-volatile memory management method according to the invention in that, the free block is not the data is written to a method of managing a nonvolatile memory having a log block to write the data for updating the data block and the data block the merge method comprising: copy the valid data from the first log block corresponding to the valid data and the first data block of the data block to generate a second block of data; And on the basis of the predetermined condition, selective allocation assigning the first data in the log block to a second log block is erased without erasing the first log block data of the allocated free block, or the first log block and a step. According to the present invention, it is possible to reduce the number of times of erasing of the memory block, it is possible to extend the use life of the flash memory is limited in the program / erase count.
