Redundancy in series grouped memory architecture |
摘要 |
An improved redundancy scheme for chained memory architecture is disclosed. The redundancy scheme comprises including redundant cells as part of the memory chain. As such, a redundant cell is used to repair a defective cell within the chain. This eliminates the need in conventional chained architecture to replace the whole memory block when there is a defective cell.
