Abstract
According to one embodiment, a storage device includes a nonvolatile memory including physical sectors each of which comprises memory cells commonly connected to a word line, each of the memory cells being capable of storing data of not less than 2 bits, each of the physical sectors including pages corresponding to the number of bits storable in the memory cell, and a controller configured to receive a first write command and to write data associated with the first write command to the nonvolatile memory. In a write process using the first write command, the controller is configured to skip an upper page of a physical sector whose lower page is write-accessed by a second write command prior to the first write command.
