    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 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 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.

    摘要: To provide an image reproducing apparatus which requires a small amount of memory capacity in reverse reproduction. The apparatus has an analyzing unit for acquiring interrelation between a plurality of items of reference image data to be referred to during decode processing from control data with a stream of encoded data, a buffer unit, and a decoding unit. An accumulation control unit uses the interrelation information obtained in the analyzing unit to extract the plurality of items of reference image data from the stream and to temporarily accumulate the same in the buffer unit. A decode control unit sequentially outputs reproduced image data decoded in the decoding unit in reverse time series as a reverse reproduction.
