1. A memory system, comprising:
a storage device including a memory device that includes a plurality of memory blocks allocated to a plurality of zones;
a memory controller that is configured to communicate with a host using a host interface and send, to the host, a request for information on whether to perform a garbage collection operation on a target zone through the host interface, in response to a trigger signal for performing a first internal operation, the target zone corresponding to a target memory block on which the first internal operation is to be performed, the target zone being included in the plurality of zones; and
the host configured to control the storage device and provide first information indicating that the garbage collection operation is to be performed on the target zone to the memory controller based on information related to the plurality of zones, in response to the request,
wherein when the memory controller receives an operation request for performing the garbage collection operation on the target zone controlled by the host from the host through the host interface, the memory controller controls the memory device to perform a second internal operation corresponding to the garbage collection operation.
