Abstract
A memory system may include a memory controller suitable for transmitting write data and a first write ECC corresponding to the write data during a write operation, a first error correction circuit suitable for detecting whether the write data received from the memory controller has an error, using the first write ECC received from the memory controller, and correcting the error when the error is detected, a second ECC generation circuit suitable for generating a second write ECC using the write data received from the memory controller, and generating the second write ECC using the write data whose error has been corrected by the first error correction circuit, when the detection of the error is noticed from the first error correction circuit, and one or more memories suitable for storing the second write ECC and write data corresponding to the second write ECC.
