摘要 |
An improved redundancy scheme for a memory matrix is disclosed. The memory matrix a plurality of memory cells interconnected in first and second directions. The memory cells are grouped into memory elements. A redundant memory element having a plurality of redundant memory cells is provided. The redundant memory element is segmented into R sections in the first direction, wherein R is a whole number greater to or equal to 2. By segmenting the redundant element into R sections, it can be used to repair defects in up to R different memory elements.
