Abstract

A memory system includes a first memory device, a second memory device, and a controller. The second memory device has a write endurance which is higher than a write endurance of the first memory device. The controller performs an error correction process on original data outputted from a host to generate a codeword including the original data and parity data. The controller separates the codeword into the original data and the parity data to write the separated original data into the first memory device and to write the separated parity data into the second memory device.
