Content addressable memory for flash redundancy
J. Jex, A. Baker · 2002
The authors describe content addressable memory (CAM) used on a 1-Mb flash memory. Yield is improved by replacing defective columns containing fatal random defects. The CAM provides the address of a redundant column as an output needed to implement column redundancy. Novel placement of the CAM can decrease redundant CAM area, decreases the total chip area, and increases the redundancy efficiency.>
