Abstract: Disclosed is a system including a memory device having a plurality of physical memory segments and a processing device to perform operations that include, responsive to detecting a failure of a memory operation associated with a physical memory segment of the plurality of physical memory segments, quarantining the physical memory segment, responsive to quarantining the physical memory segment, performing one or more scanning operations on the physical memory segment, and determining, based on results of the one or more scanning operations, a viability status of the physical memory segment, wherein the viability status indicates an ability of the physical memory segment to store data.

Abstract: A memory system includes a memory device comprising a content addressable memory (CAM) block storing a plurality of stored search keys. The memory system further includes a processing device that receives an input search key and identifies, from the plurality of stored search keys in the CAM block, multiple redundant copies of a stored search key that match the input search key. The processing device further determining whether a number of the multiple redundant copies of the stored search key that match the input search key satisfies a threshold criterion. Responsive to the number of the multiple redundant copies of the stored search key that match the input search key satisfying the threshold criterion, the processing device determines a match result for the input search key.
