Abstract
A storage device includes a plurality of nonvolatile memories each of which includes first memory cells connected to a first word line and second memory cells connected to a second word line that is adjacent to the first word line, and a controller. The controller is configured to maintain parity data for data written in the first memory cells of the nonvolatile memories, and when carrying out data writing in the second memory cells connected to the second word line in a targeted nonvolatile memory, which is one of the plurality of nonvolatile memories, upon detecting a failure in the data writing therein, carrying out restoration of data that were written in the first memory cells of the targeted nonvolatile memory using the parity data.
