Title: DEVICE AND METHOD FOR CONTROLLING REFRESH CYCLES OF NON-VOLATILE MEMORIES
Abstract:
The invention relates to a device for controlling the refresh cycles of data stored in a non-volatile memory. The device comprises a temperature sensor capable of measuring the temperature of at least one non-volatile memory and of delivering information representing the measured temperature, and a control module coupled to the temperature sensor capable of using the temperature information with modelling of the impact of the temperature on the retention time of the data in order to determine whether a loss of data is imminent and, if so, in order to generate an alarm.
