Abstract
Methods, systems, and devices for data compression for global column repair are described. In some cases, a testing device may perform a first internal read operation to identify errors associated with on one or more column planes. A value (e.g., a bit) indicating whether an error occurred when testing each column plane may be stored. The testing device may perform a second internal read operation on the same column planes, or on column planes of a different bank of memory cells. The values (e.g., bits) indicating whether errors occurred during the first internal read operation and the values indicating whether errors occurred during the second internal read operation may be combined and stored in a register. The stored values may be read out (e.g., as a burst) to repair the defective column planes.
