Abstract
An embedded memory on an integrated circuit has a memory cell array equipped with replacement cells and mapping logic for electronically substituting the replacement cells for defective cells at at least one location in the memory cell array. The memory also has programmable links for storing redundancy information in a compressed format, and decoding logic for decompressing the redundancy information and controlling the mapping logic.
