A memory system that includes an error check and correct (ECC) circuit is provided. The memory system includes a memory, the ECC circuit, and a processor. The processor controls the entire operation of the memory system. The memory includes a user data region and a management region. The management region stores access information of each of blocks in the user data region as a management table. The value of the access information is either a first value indicating that the number of access times is 0 or a second value indicating that the number of access times is greater than or equal to 1. When the value of the access information of the block is the first value, the circuit checks and corrects an error of data read from the block. When the value of the access information of the block is the second value, the circuit does not check and correct an error of data read from the block. |
