ABSTRACT:
Redundancy in a read only memory (ROM) embedded dynamic random access memory (DRAM) is accomplished by programming redundancy elements such as antifuses or registers with ROM data which is read instead of erroneous data. Multiple identical arrays of ROM bits can also be used for redundancy.
