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.

Data processing method and memory controller utilizing the same

The present invention provides a memory controller including an artificial intelligence (AI) module and a microprocessor. In the operations of the memory controller, the AI module receives a read command from a host device, and generates an auxiliary command according to the read command. The microprocessor is configured to select a first L2P mapping table according to a logical address included in the read command, and refer to the first L2P mapping table to read data from a memory module. The microprocessor is further configured to read a second L2P mapping table from the memory module according to the auxiliary command, wherein the second L2P mapping table does not include the logical address included in the read command.
