  • Publication number: 20210248064
    Abstract: A memory controller includes a memory interface and a processor. The processor is coupled to the memory interface and controls access operation of a memory device via the memory interface. The processor maintains a predetermined table according to write operation of a first memory block of the memory device and performs data protection in response to the write operation. When performing the data protection, the processor determines whether memory space damage has occurred in the first memory block. When it is determined that memory space damage has occurred in the first memory block, the processor traces back one or more data sources of data written in the first memory block according to the predetermined table to obtain address information of one or more source memory blocks and performs a data recovery operation according to the address information of the one or more source memory blocks.
