Data rate shifting based on temperature

A memory controller configured for managing data communication rates of a memory device, comprising:

• a digital memory;
• and
• a processor communicatively coupled to the memory, wherein the processor is configured to:
• execute a first memory test configured to determine performance of the memory device at a detected temperature and at each gear of a plurality of gears, wherein each gear corresponds to a respective one of a plurality of data rates used by the memory device for performing I/O operations;
• determine a first rank of one or more of the plurality of gears based on memory device performance of the first memory test;
• receive an input/output (I/O) operation to be executed by memory device:
• detect the temperature of the memory device;
• determine whether the detected temperature satisfies a threshold condition, wherein the threshold condition is satisfied if the detected temperature is above a first temperature threshold or below a second temperature threshold;
• if the threshold condition is satisfied, select a gear from the plurality of gears based on the first rank;
• and
• serve, to the memory device, the I/O operation with an indication to execute the I/O operation using the selected gear.
