Abstract
The memory controller controls at least one memory device including a plurality of stream storage areas. The memory controller comprises a buffer, a write history manager, a write controller, and a garbage collection controller. The buffer stores write data. The write history manager stores write count values for each of the plurality of stream storage areas and generates write history information indicating a write operation frequency for each of the plurality of stream storage areas based on the write count values. The write controller controls the at least one memory device to store the write data provided from the buffer. The garbage collection controller controls the at least one memory device to perform a garbage collection operation on a target stream storage area selected from among the plurality of stream storage areas based on the write history information.
