Techniques for memory operations are described. Indications of temperature levels at a memory device may be received, where each of the indications may be associated with a respective time point. Based on an indicated temperature level satisfying a first threshold, a derivative of a temperature of the memory device may be calculated using the indicated temperature levels. Based on calculating the derivative, a determination as to whether the derivative satisfies a second threshold may be determined. If the derivative satisfies the second threshold, operations for accessing the memory device may be modified. A second derivative of the temperature of the memory device may similarly be calculated and compared against a third threshold based on the indicated temperature level satisfying the first threshold. If the second derivative satisfies the third threshold, operations for accessing the memory device may be modified by a different amount.
