A resistance temperature detector includes a single channel analog to digital converter (ADC) comprising a first channel input and a reference voltage input. The detector also includes a resistance temperature detector (RTD) element connected to the first channel input and a current sense element in series with the RTD element. The current sense element is connected to the reference voltage input. The detector also includes a power source connected to the RTD element and a controller configured to: receive an output of the single channel ADC to determine a temperature at the RTD element. The output of the single channel ADC comprises a bit representation of a ratio between a first voltage across the RTD element and a reference voltage across the current sense element.

A memory system may store temperature exception tracking in a temperature log, which may be separate from data to which the temperature information corresponds. A memory device may store data in a relatively higher-level cell and the corresponding temperature information in a relatively lower-level cell. To perform a write operation, the memory system may determine a current temperature at which the data is being written or was written to a partition of a memory device and may indicate in the temperature log if the current temperature is entering a temperature range that is outside a threshold temperature (e.g., a nominal temperature). To perform a read operation, the memory system may determine if the data to read was written to the memory device outside the threshold temperature to determine whether to perform temperature compensation for the read operation.
