    摘要: According to one embodiment, a data storage apparatus comprises a first controller, a second controller, a third controller, and a fourth controller. The first controller controls a flash memory, writing and reading data, in units of blocks, to and from the flash memory. The second controller detects any a write-interrupted block is interrupted by the first controller. The third controller sets the write-interrupted block detected by the second controller, as a block to be refreshed in another block. The fourth controller performs the process of refreshing.

    摘要: According to one embodiment, a data storage apparatus includes a flash memory and a controller. The controller includes a compaction processor. The compaction processor performs the compaction processing on the flash memory, to dynamically set a range of compaction processing targets based on a number of available blocks and an amount of valid data in each of the blocks, and to search the range of compaction processing targets for blocks each with a relatively small amount of valid data as the target blocks for the compaction processing.

    摘要: 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.

    摘要: According to one embodiment, a memory controller comprises a counter and a setting module. The counter is configured to count the number of valid pages in a block includes a page to be invalidated, when data is written in a nonvolatile memory. The setting module is configured to set the block as an object of compaction when the number of valid pages counted by the counter is smaller than a predetermined number.
