Abstract:
According to one embodiment, a memory system manages a plurality of management tables corresponding to a plurality of first blocks in a nonvolatile memory. Each management table includes a plurality of reference counts corresponding to a plurality of data in a corresponding first block. The memory system copies, based on a first management table corresponding to a copy-source block for garbage collection, only data corresponding to reference counts of non-zero from the copy-source block to a copy-destination block, and associates physical addresses respectively indicating locations in the copy-destination block, in which the data are copied, with respective intermediate addresses corresponding to the copied data.

Claim (Index 10):
The method of  claim 8 , further comprising:\n managing a third translation table managing a corresponding relationship between hash values and the intermediate addresses; obtaining a hash value of the write data; executing, when intermediate address corresponding to the obtained hash value does not exist in the third translation table, an operation of determining that the redundant data which agrees with the write data does not exist in the nonvolatile memory and assigning an non-use intermediate address to the obtained hash value, and an operation of storing a corresponding relationship between the obtained hash value and the intermediate address assigned to the obtained hash value in the third translation table, and wherein when the redundant data which agrees with the write data does not exist in the nonvolatile memory, the intermediate address assigned to the obtained hash value is associated with the logical address of the write data as the first intermediate address.
