Abstract
The NVDIMM () comprises a DRAM (), a NAND flash memory () and a NVDIMM controller (), the NVDIMM controller () controlling the NVDIMM () and comprising a DDR controller (), a NAND flash memory controller (), a data backup module () and a data recovery module (), and the DDR controller () using and enabling DBI. The backup method comprises: reading, by the DDR controller (), N-bit DQ and 1-bit DBI from the DRAM () and sending the same to the data backup module; encoding, by the data backup module (), the N-bit DQ and the 1-bit DBI into N-bit EDQ according to the values of the N-bit DQ and the 1-bit DBI, and sending the N-bit EDQ to the NAND flash memory controller; and receiving, by the NAND flash memory controller (), the N-bit EDQ and writing the N-bit EDQ into the NAND flash memory ().
