Abstract
An operation method of a memory system including a memory controller and a memory device may include transferring, by the memory controller, a first read command to the memory device; transferring, by the memory device, read data and a part of an error correction code corresponding to the read data to the memory controller in response to the first read command; detecting, by the memory controller, an error of the read data based on the part of the error correction code; transferring, by the memory controller, a second read command to the memory device when the error is detected; transferring, by the memory device, a remainder of the error correction code corresponding to the read data to the memory controller in response to the second read command; and correcting, by the memory controller, the error of the read data based on the remainder of the error correction code.
