Memory system and method of operating the same

A memory system including a plurality of zones for storing data, comprising:

• a memory device including a plurality of memory blocks corresponding to the plurality of zones;
• and
• a memory controller coupled to the memory device and configured to control the memory device in performing a write operation in the memory device,
• wherein the memory controller is configured to:
• upon performing a write operation corresponding to a write request received from a host, update a logical write pointer and a physical write pointer associated with a zone that is targeted to perform the write operation corresponding to the write request received from the host, and
• upon performing a write operation corresponding to an internal write command internally issued by the memory controller, update a physical write pointer associated with the zone that is targeted to perform the write operation corresponding to the internal write command issued by the memory controller,
• wherein the physical write pointer indicates a physical location where a write operation has been most recently performed in the memory device.
