摘要： According to one embodiment, a memory system includes a non-volatile semiconductor memory, a block management unit, and a transcription unit. The semiconductor memory includes a plurality of blocks to which data can be written in both the first mode and the second mode. The block management unit manages a block that stores therein no valid data as a free block. When the number of free blocks managed by the block management unit is smaller than or equal to a predetermined threshold value, the transcription unit selects one or more used blocks that stores therein valid data as transcription source blocks and transcribes valid data stored in the transcription source blocks to free blocks in the second mode.

摘要： A storage system connectable to a host includes a plurality of interface units, a plurality of semiconductor memory modules, each being detachably coupled with one of the interface units, and a controller configured to maintain an address conversion table indicating mappings between logical addresses and physical addresses of memory locations in the semiconductor memory modules. When the controller determines that a first semiconductor memory module needs to be detached, the controller converts physical addresses of the first semiconductor memory module into corresponding logical addresses using the address conversion table and copies valid data stored in the corresponding logical addresses to another semiconductor memory module and update the address conversion table to indicate new mappings for the corresponding logical addresses of the valid data.

摘要： According to one embodiment, a data storage device includes a first storage unit, a second storage unit, a first queue, a second queue, and a distributor. The second storage unit is used as a cache of the first storage unit and has a lower write transfer rate and a faster response time than the first storage unit. The first queue corresponds to the first storage unit. The second queue corresponds to the second storage unit. The distributor distributes a write command received presently from a host to one of the first and second queues in which the number of write commands registered presently is smaller.

摘要： According to an embodiment, a controller includes a write control unit configured to make a control that converts data requested to be written by an external device into pieces of cluster data with a size of a cluster of a storage medium, compresses each piece of cluster data, determines a corresponding physical address of a write destination in the storage medium according to a predetermined rule, and writes the compressed pieces of cluster data to the storage medium using the physical address of the write destination. The write control unit also makes a control that writes a correspondence between the physical address and a corresponding logical address to a storage unit. The controller also includes a read control unit configured to a control that reads a piece of cluster data from the storage medium using an acquired physical address, and decompresses the read piece of cluster data.
