Abstract: A data processing method includes: configuring a predetermined memory space to record information regarding valid data of a memory device, where the information is used to indicate data associated to which logical memory spaces of the memory device is valid; and updating the information according to commands received from a host device.

Abstract: 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 read command according to the read command. The microprocessor reads first data from a memory module according to the read command, and reads second data from the memory module according to the auxiliary read command, wherein a logical address the second data is not recorded in the read command.
