Abstract
A memory system includes a non-volatile memory. A coding unit generates a codeword by performing coding of a graph code using a graph. A side of the graph is associated with a block that is a part of user data and that has one or more symbols at which component codes intersect one another. A control unit stores the codeword in the non-volatile memory. Error correction is performed on the user data in accordance with the codeword.
