Abstract:
According to one embodiment, a write instructing unit instructs a data access unit to write, in a storage area of a data storage unit indicated by a first physical address, write object data, instructs a management information access unit to update address conversion information, and instructs a first access unit to update the first physical address. A compaction unit extracts a physical address of compaction object data, instructs the data access unit to read the compaction object data stored in a storage area of the data storage unit indicated by the physical address, instructs the data access unit to write the compaction object data in a storage area of the data storage unit indicated by a second physical address, instructs the management information access unit to update the address conversion information, and instructs a second access unit to update the second physical address.

Claim (Index 9):
A memory system comprising:\n a nonvolatile semiconductor memory comprising a plurality of blocks, the blocks including one or more first blocks, a plurality of second blocks which differ from the first blocks, and a third block, each of the blocks being a unit of an erase operation of the nonvolatile semiconductor memory; and a controller circuit configured to receive a write request from a host device, the write request including a size of first data to be written to the memory system; wherein the controller circuit is configured to perform a write operation of the first data to the first blocks in response to the write request; the controller circuit is configured to perform a compaction operation of reallocating second data stored in the second blocks to the third block which stores no valid data and treating the second blocks as free blocks; the controller circuit is configured to switch, while continuously performing one of the compaction operation and the write operation, the operation to the other of the compaction operation and the write operation.
