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).

Salvaging bad blocks in a memory device

A method of operating a memory device comprises generating a target voltage using a pump circuit of the memory device, the target voltage to be applied to a word line or pillar of a memory cell of the memory device; providing an indication of current generated by the pump circuit after the pump circuit output reaches the target voltage; and determining when the current generated by the pump circuit is greater than a specified threshold current and generating a fault indication according to the determination.

Device field degradation and factory defect detection by pump clock monitoring

A processing device in a memory system receives a request to erase a data block of a memory device, determines a number of program/erase cycles performed on the data block, and performs an erase operation to erase the data block. The processing device further determines that the number of program/erase cycles performed on the data block satisfies a scan threshold condition and performs a first threshold voltage integrity scan on the data block to determine a first error rate associated with a current threshold voltage of at least one select gate device of the data 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.
