the present invention relates to a circuit and a method for improving operation life of original various internal or external nonvolatile memories by means of long - life nonvolatile memory chips . in the case that the hardware structure , interface type , packaged type and operation condition of existing various nonvolatile memories are not changed yet , only long - life nonvolatile memory chips are added into original hardware structure , and correspondingly , long - life nonvolatile memory addresses are added into original memory addresses in main boot - block for the memories , the original device driver or operating system is modified , so as to increase operation life of the memories greatly .
