SYSTEMS AND METHODS FOR FINE GRANULARITY MEMORY SPARING

摘要

Systems and methods for fine-grained sparing in non-volatile memories art disclosed. A system may include a memory having a plurality of blocks, a plurality of tags and a plurality of spared lines, wherein each of the tags corresponds to one of the plurality of spared lines, and table having a plurality of machine addresses, wherein each machine address corresponds to a sparing area for each of the blocks of the plurality of blocks. Methods of operation a fine-grained sparing system are also disclosed.
