Abstract
A redundancy architecture for a memory includes an array of memory cells divided into at least a pair of semi-arrays that are singularly addressable. Each semi-array is organized into rows and columns. The redundancy architecture includes a number of packets each including redundancy columns. The packets are divided into two subsets of packets. Each packet is addressable independently from the other by respective address circuits. Each packet also provides redundancy columns exclusively for a respective semi-array.
