Abstract
A memory system includes a cache module configured to store data. A duplicate removing filter module is separate from the cache module. The duplicate removing filter module is configured to receive read requests and write requests for data blocks to be read from or written to the cache module, selectively generate fingerprints for the data blocks associated with the write requests, selectively store at least one of the fingerprints as stored fingerprints and compare a fingerprint of a write request to the stored fingerprints.
