Read voltage calibration based on host io operations

A memory device, comprising:

• a memory array comprising groups of multiple blocks of memory cells;
• and
• a controller operably coupled to the memory array, the controller configured to perform operations comprising:
• monitoring read operations occurring to a respective block of the memory array;
• identifying, based at least in part on the read operations occurring to the respective block, a condition to trigger a read level calibration;
• and
• performing, in response to the identified condition, the read level calibration on the memory array, wherein the read level calibration comprises a sampling operation configured to evaluate a threshold voltage level among a group of multiple blocks of the memory array including the respective block.
