Storage device, method of operating the same, and computing system including the storage device

A storage device, comprising:

• a memory device including a plurality of memory areas;
• and
• a memory controller in communication with the plurality of memory devices to control the memory device in processing a request of a host device in accessing the plurality of memory devices,
• wherein the memory controller is configured to:
• allocate the plurality of memory areas to a plurality of functions;
• allocate a plurality of request slots corresponding to at least part of the plurality of memory areas available for dealing with the request of the host device per unit time to each of the plurality of functions,
• determine idle request slots other than active request slots that are being used to process the request of the host device among the plurality of request slots allocated to each of the plurality of functions;
• and
• control an internal operation of the memory device based on at least one target function associated with the idle request slots, among the plurality of functions.

A method of operating a storage device, the method comprising:

• allocating a plurality of request slots corresponding to at least part of memory resources in the storage device, to a plurality of functions;
• receiving a request of a host device;
• allocating the received request to the plurality of request slots allocated to a function of the plurality of functions corresponding to the received request;
• performing a host-requested operation corresponding to the received request based on active request slots allocated the received request;
• detecting a condition for performing an internal operation;
• and
• performing the internal operation based on at least one target function associated with idle request slots to which the received request is not allocated, among the plurality of functions.
