THE METHOD FOR THE DATA SWAPPING BETWEEN THE BLOCKS OF NON VOLATILE MEMORY DEVICE

摘要

A method for exchanging data between blocks of a nonvolatile memory device is provided to improve data exchange speed by exchange data between blocks included in an equal memory cell array without using an additional external memory. A block data exchange command and an address of a first block and a second block included in an equal memory cell array are inputted(210). An address of a temporal block, for storing the first block data, included in the same memory cell array where the first block is read out from a selected point of a spare cell included in the memory cell array(216). Data of the first block is stored in the temporal block temporarily. Data stored in the first block is stored in the temporal block(218). Data stored in the second block is stored in the first block(220). Data stored in the temporal block is stored in the second block(222).
