Abstract
A storage device that can be connected to a host device includes a plurality of nonvolatile memories. Each nonvolatile memory includes first memory cells connected to a first word line and second memory cells connected to a second word line. The second word line is adjacent to the first word line. A method of operating the storage device includes maintaining parity data for the data that has been written to the first memory cells, and, upon detecting a failure in the writing of data to the second memory cells, restoring the data written to the first memory cells using the parity data.
