A memory system includes a memory module that includes a first memory device through a fourth memory device and a first error correction code (ECC) device, and a memory controller that exchanges first user data with each of the first memory device through the fourth memory device through 8 data lines and exchanges first ECC data with the first ECC device through 4 data lines. The memory controller includes an ECC engine that corrects a 32-random bit error of the first user data, based on the first ECC data.

Memory module, memory system, and operation method of memory controller

A memory system including a first central processing unit, a first memory module connected to the first central processing unit by a first channel, a second memory module connected to the first central processing unit by a second channel, and a third memory module connected to the first central processing unit by a third channel may be provided. Each of the first memory module, the second memory module, and the third memory module may be configured to write the same data in a data area thereof and a mirroring data area thereof in response to an address in a mirroring mode.
