Abstract
According to one embodiment, a storage device includes a nonvolatile memory and a controller. The controller is configured to select a first mode as a write mode to write data from the host to the nonvolatile memory when the controller receives a first instruction from the host. In the first mode, n-bit data is written into a memory cell in a first area of the nonvolatile memory, n being a positive integer more than or equal to 1. The controller is configured to select another mode different from the first mode as the write mode when the controller receives a second instruction from the host.
