Abstract
A data storage system performs partial compression and decompression of a set of memory items. The memory items each include a data block and a tag with a prefix making up at least part of the tag. The memory items are ordered based on the prefixes. A code word is created containing compressed information representing values of the prefixes for the set of memory items. The code word and block data for each of the memory items are stored in a memory. The code word is decompressed to recover the prefixes.
