Abstract
According to one embodiment, a data storage apparatus comprises a channel controller, an encoding module, and a data controller. The channel controller is configured to control data input to, and output from, nonvolatile memories for channels. The encoding module is configured to generate encoded data for which an inter-channel error correction process, using data stored in each of the nonvolatile memories. The data controller is configured to manage the encoded data in units of logic 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 one plane in each logic block.
