Abstract
Methods, systems, and devices for evaluation of memory device health monitoring logic are described. A memory device may include health monitoring logic that is operable to be enabled in a configuration that corresponds to an output, such as an expected output, regardless of a degradation level of the memory device. Such a configuration may be enabled in a mode, such as a test mode, during which the memory device, or a host device coupled with the memory device, or some combination, may evaluate a difference between the output and an actual output of the health monitoring logic. The actual output being the same as the output may provide an indication that at least a portion of the health monitoring logic is functioning properly, and the actual output being different than the output may provide an indication that at least a portion of the health monitoring logic is not functioning properly.
