Abstract: An improved redundancy architecture for embedded memories in an ASIC chip includes one or more compiler-generated embedded memory instances. Each embedded memory instance has a universal register for storing an address of a defective subunit of the memory instance from a variety of sources. A control block is located on the ASIC chip outside of the memory instances. The control block has a defective memory register for storing an address of a defective memory subunit. The address of a defective memory subunit from the defective memory register in the control block is transferred to the universal interface register in the memory instance. In one embodiment, the control block includes fuses for storing a defective subunit address in binary form. A fuse array is located outside of the memory instances and contains laser fuses that represent address of defective subunits for each memory instance.
