Abstract
A dynamic column redundancy replacement system for programming and reading a non-volatile memory system includes an input data replacement logic block and an output data replacement logic block. A column redundancy match logic block compares a user address to latched fuse addresses of bad columns and identifies address matches to facilitate the replacement of bits from defective memory cells with replacement redundancy bits.
