Abstract

A memory system includes a memory device configured to store data, and read and output the stored data in a read operation, and a memory controller configured to perform an error correction operation on the data received from the memory device in the read operation and control the memory device to perform a read retry operation, based on the result of the error correction operation. The memory device outputs the data read in the read retry operation to the memory controller when the number of specific data, among data read in the read retry operation, is in a set range. Only reliability-ensured data in the read retry operation is output to the memory controller. Thus, the number of times of outputting data to the memory controller can be decreased, and the number of times where the memory controller performs an error correction operation can be decreased.
