1. A memory system comprising,
a memory device storing data; and
a memory controller configured to:
determine status information of the memory system,
generate a frame used for a flow control at a data link layer between a host and the memory system, and including a sequence number for data received by the memory system and the status information, and
transmit the frame to the host while the host is performing communication with the memory system through the data link layer,
wherein the memory controller is configured to generate the frame by:
writing the status information of the memory system to at least one status information register included in the memory system by executing an interrupt service routine for processing interrupt indicating a change of the status information, and
storing, in the frame, the status information of the memory written in the status information registers.
