Efficient management of failed memory blocks in memory sub-systems

A system comprising:

• a memory device comprising a plurality of physical memory segments;
• and
• a processing device, operatively coupled with the memory device, to perform operations comprising:
• responsive to detecting a failure of a read memory operation associated with a physical memory segment of the plurality of physical memory segments, determining a bit error rate for at least some partitions of the physical memory segment to make a determination of whether data stored in the physical memory segment is safe, lost, or at risk of being lost;
• select, based on the determination of whether the data stored in the physical memory segment is safe, lost, or at a risk of being lost, one or more scanning operations for the physical memory segment;
• performing the one or more selected 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.

A method comprising:

• detecting, by a processing device operatively coupled with a memory device, a failure of a memory operation associated with a physical memory segment of the memory device, the memory device having a plurality of physical memory segments;
• quarantining, by the processing device, the physical memory segment;
• responsive to quarantining the physical memory segment, performing, by the processing device, 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.
