1. A storage device comprising:
a main memory comprising a first segment in which a refresh operation is configured to be enabled, and a second segment that is masked so as to be configured to disable the refresh operation;
a cache memory configured to store some metadata stored in the main memory; and
a memory controller configured to control the main memory, so as to have dirty metadata stored in the second segment in response to a cache miss occurring, and to logically move the dirty metadata from the second segment to the first segment by mapping a physical address of the second segment in which the dirty metadata is to be stored to a physical address of the first segment.
