Abstract
Dynamic redundancy registers for use with a device are disclosed. The dynamic redundancy registers allow a memory bank of the device to be operated with high write error rate (WER). A first level redundancy register (e1 register) is couple to the memory bank. The e1 register may store data words that have failed verification or have not been verified. The e1 register may transfer data words to another dynamic redundancy register (e2 register). The e1 register may transfer data words that have failed to write to a memory bank after a predetermined number of re-write attempts. The e1 register may also transfer data words upon power down.
