Apparatus and method for preventing data loss of non-volatile memory

The present invention relates to an apparatus and method for preventing data loss in non-volatile memory, and more particularly, to avoid loss of data in non-volatile memory that can indicate the bit information for a number of pages with a single memory cell, to an apparatus and method for preventing data loss in non-volatile memory that can. Device for preventing the loss of data in non-volatile memory according to an embodiment of the present invention, at least two through the plurality of conditions are implemented bits of recording the bit information for the first page and a second page included in the first block non-volatile memory including memory cells; And a data processing unit for recording the bit information of the first page at the time of information recording bits of information bits and then writing of the first page, the second page in a second block of the nonvolatile memory. Non-volatile memory, MLC, LSB, MSB
