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 4):
The memory system of  claim 3 , wherein\n the controller is configured to: acquire, when intermediate address corresponding to the obtained hash value already exists in the third translation table, a physical address associated with the intermediate address corresponding to the obtained hash value by referring to the second translation table; compare the write data with first data stored in the location in the nonvolatile memory, which is designated by the acquired physical address; and determine, when the write data and the first data agree with each other, that the redundant data which agrees with the write data already exists in the nonvolatile memory, and wherein when the redundant data which agrees with the write data already exists in the nonvolatile memory, the intermediate address which corresponds to the obtained hash value and already exists in the third translation table is associated with the logical address of the write data as the second intermediate address.
