Replacing rows or columns that contain defective memory cells with spare rows or columns prepared in advance. The defect locations are found by testing and the switch is made with fuses or similar. It greatly improves yield.
Field: DRAM
Without this redundancy repair, high-capacity DRAM yields would be untenable.
Which correctly describes redundancy repair, used to improv…It is used to compute redundancy repair, replacing failing rows or columns with spares, and the pattern of failures (single bits, whole rows, clusters and so on) also helps infer what kind of manufacturing defect is responsible.
