Abstract
According to one embodiment, a memory system includes a non-volatile memory, a memory interface, an encoder configured to generate eight code words, and a writing control unit. The writing control unit causes the memory interface to perform a first writing and a second writing, and repeat the first writing and the second writing. The first writing writes a first symbol included in a first code word to a second page in a first word line. The second writing writes a second symbol included in a first code word to a first page in a third word line adjacent to a second word line adjacent to a first word line. Thus, the code words to be written are changed. The repeat of the first writing and the second writing is performed by shifting a word line at a write destination one by one.
