Method for sensing temperature in memory die, memory die and memory with temperature sensing function

A memory with temperature sensing function, comprising:

• at least one memory die;
• and
• a host controller, provided outside the at least one memory die and coupled to the at least one memory die for controlling the at least one memory die,
• wherein the at least one memory die comprises:
• a memory array;
• at least one temperature monitoring pin, provided on and outside the memory die and configured to output a temperature status in the at least one memory die;
• a temperature sensor, arranged in the at least one memory die for sensing an operation temperature in the at least one memory die;
• and
• a control logic unit, coupled to the memory array and the temperature sensor, wherein the control logic unit is configured to receive the operation temperature and receive a specific command from the host controller, and coupled to the at least one temperature monitoring pin, wherein the specific command comprises at least one threshold value,
• the control logic unit is configured to compare the operation temperature with the at least one threshold value to generate a comparison result, and is configured to output the temperature status to the host controller through the at least one temperature monitoring pin according to the comparison result.

A method for sensing a temperature status in a memory die with at least one temperature monitoring pin that is provided on and outside the memory die, a temperature sensor being provided in the memory die to sense an operation temperature in the memory die, and the method comprising:

• receiving a specific command from outside of the memory die, wherein the specific command comprises at lase one threshold value;
• comparing the operation temperature with the at least one threshold value to generate a comparison result;
• and
• outputting the temperature status corresponding to the comparison result to a host controller coupled to and outside of the memory die through the at least one temperature monitoring pin of the memory die.

A host controller for controlling a memory die, wherein at least one temperature monitoring pin is provided on and outside the memory die, and the host controller is outside of the memory die, the host controller is configured to

• issue a specific command to the memory die in a command cycle;
• receive a ready status from the memory die after the specific command is received by the memory die, wherein the ready status indicates that the memory die for reception from the host controller;
• send at least one threshold value to the memory die in a data cycle subsequent to the command cycle;
• and
• receive a temperature status through the at least one temperature monitoring pin from the memory die, wherein the temperature status corresponds to a comparison result between the at least one threshold value and an operation temperature of the memory die, and the comparison result is generated by a control logic unit of the memory die.
