Abstract
A memory controllerof a memory systemaccording to an embodiment is provided with an encoding deviceand a memory interface. The encoding deviceis provided with an encoderwhich generates a plurality of first parities by encoding a plurality of user data by using a common code, an interleaverwhich sequentially interleaves the plurality of user data, and an XOR accumulatorwhich sequentially executes component-wise modulo-2 operation on the interleaved plurality of user data. The encodergenerates second parity by encoding a result finally obtained by executing the component-wise modulo-2 operation on a plurality of user data. The memory interfacewrites a code word sequence including the plurality of user data, the first parities and the second parity in a non-volatile memory
