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 16):
A method that is used for a controller circuit of a memory system, the memory system comprising 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;\n the method comprising: receiving a write request from a host device, the write request including a size of first data to be written to the memory system, performing a write operation of the first data to the first blocks in response to the write request; performing 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; switching, 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.
