Abstract
A controller is provided. The controller includes a write queue configured to store commands for operating a memory device that are generated based on requests received from a host, zone identifications of the commands each indicating a memory region in the memory device to store data corresponding to a command, and write pointers of the commands each indicating an order that the requests are output from the host; and a queue controller configured to receive the commands, the zone identifications, and the write pointers from the write queue, store the commands in buffers allocated the zone identifications based on the write pointers, respectively, and based on an occurrence of an event that a number of commands stored in a buffer among the buffers reaches a preset number set in the buffer, output commands stored in the buffer.
