Various methods and apparatuses are described in which a repair data
container may store a concatenated repair signature for multiple memories
having one or more redundant components associated with each memory. A
processor contains redundancy allocation logic to execute one or more
repair algorithms to generate a repair signature for each memory. The
repair data container may store actual repair signatures for each memory
having one or more defective memory cells detected during fault testing
and dummy repair signatures for each memory with no defective memory
cells. The processor may contain logic configured to compress an amount
of bits making up the concatenated repair signature, to decompress the
amount of bits making up the concatenated repair signature, and to
compose the concatenated repair signature for all of the memories sharing
the repair data container. The repair data container may have an amount
of fuses to store the actual repair signatures for an adjustable subset
of the multiple memories.
