According to one embodiment, a semiconductor storage device includes a queuing buffer, a read module, a separating module, a write command issuing module, and a write module. The write command issuing module is configured to add a write address indicated by write pointer information to the management data obtained by the separating module in order to issue a write command, and to automatically queue the write command into the queuing buffer. The write module is configured to supply the write command issued by the write command issuing module to the nonvolatile memory in order to write data into the nonvolatile memory.

According to one embodiment, a data storage apparatus includes a memory module and a controller. The memory module has a plurality of flash memory chips. Data is written to or read from each flash memory chip having a specific page size as access unit. The controller is configured to supply memory control signals, which are independent of the common signal containing the data and addresses, to the flash memory chips, respectively, in order to write data larger than the specific data size to the memory module. In the memory module, the respective flash memory chips store the data, each at the same address, in response to the memory control signals.

According to one embodiment, a memory control device includes a controller, a command queue module, a plurality of stage processors, and a skip module. The controller controls a data access command to a nonvolatile memory from a host. The command queue module queues a transfer request command corresponding to the data access command. The stage processors each perform stage processing related to the transfer request command queued by the command queue module. The skip module skips the stage processing by the stage processors in response to a shutdown command from the controller.

According to one embodiment, a memory control device includes a first controller, a second controller, an access module, and a response sort module. The first controller controls processing of a data access command to a nonvolatile memory from a host. The second controller controls processing assigned to the second controller between the first controller and the second controller. The access module performs data access to the nonvolatile memory in response to a command from the first controller or the second controller. When an error occurs in the data access by the access module, the response sort module returns a response to the second controller instead of the first controller.

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.
