According to one embodiment, a data storage apparatus comprises a channel controller, an encoding module, and a data controller. The channel controller configured to control data input and output to and from nonvolatile memories for channels. The encoding module configured to generate encoded data for an interchannel error correction process, using data stored in each of the nonvolatile memories. The data controller configure to manage the encoded data in units of logical blocks when the channel controller writes the encoded data in parallel to the channels, and to allocate parity data contained in the encoded data to planes of the same channel in each logical block.
