A memory controller for controlling access to a flash memory including a plurality of physical blocks, each of which includes a plurality of pages, based on a command assigned from a host system. The memory controller stores a first correspondence relationship between a logical block of a first logical region and a physical block of a first physical region in a first storage unit. The memory controller manages the first physical region in which a process of moving data saved in the physical block of the first physical region having the correspondence relationship with the logical block of the first logical region is prohibited without being based on a command for writing the data to the first logical region assigned from the host system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Memory controller and memory system","description":"A memory controller capable of preventing important data stored in a flash memory from being lost and maintaining the quality of a physical block.
