摘要： According to one embodiment, a memory device includes a memory, a memory interface, a command generator, an access command returning module and a command progress manager. The memory interface accesses the memory in parallel in accordance with access commands. The command generator speculatively issues access commands to the memory interface. The access command returning module returns access commands already issued to the memory interface and unexecuted at a time of occurrence of an error, through corresponding purge responses. The command progress manager updates command progress management information such that the command progress management information indicates the oldest one of the unexecuted access commands. The command generator reissues the returned unexecuted access commands to the memory interface based on the updated command progress management information.

摘要： According to one embodiment, a valid-cluster search module searches valid clusters included in first blocks, in each of channels, for compaction. A read command generator generates read commands used to read, in parallel, valid clusters to be migrated to a second block. The valid clusters searched in each of the channels comprise the valid clusters to be migrated. The valid clusters to be migrated correspond to a number of clusters simultaneously written to the second block and to a second number of channels in a first number of channels. A determination module determines the second number of channels corresponding to read commands to be generated next based on a situation of issuance of the read commands.

摘要： According to one embodiment, a data storage apparatus includes a first memory configured to store a first management table, a second memory configured to store a second management table, a counter table memory, and a controller. The first management table has address data representing a storage position of data stored in a flash memory. The second memory has address data representing valid data included in the data stored in the flash memory. The counter table memory stores a counter table showing the count value of valid data in units of addresses. The controller is configured to refer to the first management table, to compare the number of data valid in units of addresses acquired by referring to the first management table, and to perform a matching check process for determining matching between the first and second management tables from a result of the comparison.

摘要： According to one embodiment, a storage controller includes a condition storage, a determination module, a wear-leveling block retainer, and a data transfer controller. The condition storage is provided in a storage including a plurality of blocks, and stores block condition information including at least one of erasure time information indicating when data is erased last time and erasure count information indicating the number of times data is erased. The determination module determines whether there is a block that requires wear leveling based on the block condition information. The wear-leveling block retainer retains block identification information that identifies a block determined to require wear leveling. The data transfer controller performs compaction to transfer data stored in blocks of the storage for collecting the data in a block, and, when the block identification information is retained, transfers data stored in the block identified by the block identification information.

摘要： According to one embodiment, a command generator sequentially and speculatively issues channel-by-channel access commands to a memory interface in a predetermined access process. A purger returns a series of unexecuted already-issued access commands using a purge response if an error occurs in any of memory accesses via a plurality of channels. A command progress manager updates command progress information such that the command progress on each of the plurality of channels returns to a position specified in an oldest access command of a series of the returned access commands issued to the channel. The command generator issues the channel-by-channel access commands including the oldest access command to the memory interface based on the updated command progress information.
