Methods, Devices and Systems for an Improved Management of a Non-Volatile Memory

A memory device comprising:

• a non-volatile memory;
• and
• an operating unit of the non-volatile memory,
• wherein the operating unit is configured to:
• obtain a plurality of temperature values of at least one region of the non-volatile memory, each temperature value being obtained at a given time instant;
• for each obtained temperature value at each given time instant, calculate the value of an operating function representative of an operating condition of the non-volatile memory, the value of said operating function being time-dependent according to a temperature time-variation of said at least one region of the non-volatile memory;
• sum subsequent calculated values of said operating function to obtain an accumulated value being representative of an elapsed fraction of a time limit associated with said at least one region of the non-volatile memory;
• compare the accumulated value with a threshold value;
• and
• based on said comparison, perform a management operation on a memory cell of said at least one region of the non-volatile memory when the accumulated value has a magnitude equal to or greater than the threshold value.

A system comprising:

• a host device;
• a controller;
• and
• a memory device including a non-volatile memory,
• wherein the controller is configured to:
