Abstract: Disclosed in some examples are methods, systems, devices, memory devices, and machine-readable mediums for using a non-defective portion of a block of memory on which there is a defect on a different portion. Rather than disable the entire block, the system may disable only a portion of the block (e.g., a first deck of the block) and salvage a different portion of the block (e.g., a second deck of the block).

Responsive to the first error rate associated with the current threshold voltage of the at least one select gate device satisfying an error threshold criterion, the processing device performs a touch up operation on the at least one select gate device to adjust the current threshold voltage to the target threshold voltage.
