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