Abstract

See full text

According to an embodiment, a memory system includes: a non-volatile memory; an encoding unit that generates a code word in which zero and one occur at different occurrence rates by encoding data; and a control unit that writes k third data items and fourth data items into the non-volatile memory. The k is an integer larger than or equal to zero and smaller than or equal to n. The n is an integer larger than or equal to two. The k third data items are obtained by encoding k second data items with the encoding unit among first data items including n second data items and having a first data length. The fourth data items are obtained by removing data corresponding to the k third data items from the first data items. The third data items are generated by encoding the second data items with encoders, respectively.
