The controller includes a request analyzer, a storage, and a garbage collection controller. The request analyzer generates invalid data information, based on an erase request received from a host. The storage stores a garbage collection reference table representing memory blocks excluded from selection as a victim block on which a garbage collection operation is to be performed, based on the invalid data information. The garbage collection controller controls the garbage collection operation on the semiconductor memory device, based on exclusion block information generated according to the garbage collection reference table."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Controller and memory system for performing garbage collection operation, and operating method thereof","description":"A controller controls an operation of a semiconductor memory device.
