Abstract: A memory system includes a memory device. A buffer memory is configured to store at least one of a ready-to-transfer (RTT) UFS-Protocol-Information-Unit (UPIU) and a response UPIU. The buffer memory is implemented separately from the memory device. A memory controller is configured to acquire read data from the memory device in response to a read request received from an external host and transmit a read data packet including the read data to the external host. When the at least one of the ready-to-transfer UPIU and the response UPIU stored in the buffer memory is present, the memory controller sends the at least one of the ready-to-transfer UPIU and the response UPIU to the external host, before a transmission of the read data packet is completed.
