SYSTEMS AND METHODS FOR FINE GRANULARITY MEMORY SPARING

摘要

Systems and methods for fine-grained sparing in non-volatile memories (48) are disclosed. A system (10) may include a memory (48) having a plurality of blocks, a plurality of tags (110) and a plurality of spared lines (102), wherein each of the tags (110 corresponds to one of the plurality of spared lines (102), and a table (74) having a plurality of machine addresses (76), wherein each machine address (76) corresponds to a sparing area (100) for each of the blocks (84) of the plurality of blocks. Methods of operation of a fine-grained sparing system (70, 100) are also disclosed.
