Temperature monitoring for memory devices

A memory device, comprising:

• an array of memory cells;
• one or more temperature sensors configured to output a plurality of temperatures associated with the array while the memory device operates over one or more power cycles;
• circuitry coupled with the one or more temperature sensors and configured to determine, for each temperature, a corresponding temperature range of a plurality of temperature ranges;
• a plurality of counters coupled with the circuitry, each counter of the plurality of counters associated with a corresponding temperature range of the plurality of temperature ranges and configured to determine a corresponding time duration over the one or more power cycles that the memory device is operating within the corresponding temperature range based at least in part on the counter incrementing by a value indicating the corresponding time duration;
• and
• a storage component coupled with the plurality of counters and configured to store the values associated with the plurality of counters.

A method by a memory device, comprising:

• receiving, while the memory device operates over one or more power cycles, a plurality of temperatures from one or more temperature sensors of the memory device;
• determining, at circuitry of the memory device and for each temperature, a corresponding temperature range of a plurality of temperature ranges, each temperature range of the plurality of temperature ranges being associated with a respective counter of a plurality of counters;
• determining, for each corresponding temperature range, a corresponding time duration over the one or more power cycles that the memory device is operating within the corresponding temperature range by incrementing a respective counter of the plurality of counters associated with the corresponding temperature range by a value indicating the corresponding time duration;
• and
• storing the values associated with the plurality of counters at a storage component associated with the memory device.
