Abstract

Methods, systems, and devices for adjustable column address scramble using fuses are described. A testing device may detect a first error in a first column plane of a memory array and a second error in a second column plane of the memory array. The testing device may identify a first column address of the first column plane associated with the first error and a second column address of the second column plane based on detecting the first error and the second error. The testing device may determine, for the first column plane, a configuration for scrambling column addresses of the first column plane to different column addresses of the first column plane. In some cases, the testing device may perform a fuse blow of a fuse associated with the first column plane to implement the determined configuration.
