Abstract

The invention discloses a method and a system for restoring starting information of a memory device. The memory device startup information restoration system includes a memory device and an electronic device. The memory device comprises a nonvolatile memory, and the nonvolatile memory comprises a plurality of good blocks and a plurality of damaged blocks. The electronic device comprises card activating software for executing the method for restoring the starting information of the memory device, and the method comprises the following steps of: acquiring non-volatile memory damaged block address data corresponding to the memory device by the card activating software according to an exclusive serial number and a mapping table; the card activating software enables the memory device to erase the good blocks in the nonvolatile memory according to the address data of the damaged blocks of the nonvolatile memory; the card activating software generates user system data, and the memory device writes the user system data into the nonvolatile memory.

Description

technical field [0001] The present invention relates to a method and a system for restoring boot information of a memory device, in particular to a method for indexing and obtaining the damaged block address data of a non-volatile memory of a corresponding memory device according to an exclusive serial number and a mapping table, and encoding it A method and system for restoring boot information of a memory device based on which user system data is generated. Background technique [0002] Generally, a storage device (eg, a solid state drive) includes a controller and non-volatile memory (eg, flash memory), where the non-volatile memory is used to store data. When memory manufacturers manufacture non-volatile memories, it is inevitable that some non-volatile memories do not meet the original factory specifications and are listed as downgrades. Therefore, before these substandard products are assembled into products, a card opening (initialization) step needs to be performed ...
