Abstract:
Methods, systems and computer program products for extending the shelf life of non-volatile memory devices, aspects of which include detecting that the non-volatile memory device has been disconnected from a power supply and responsively resetting a timer, a first counter, and a second counter and incrementing the first counter and the second counter based on the timer. Based on a determination that the first counter has reached a first threshold value, aspects also include initiating a wireless charging a battery of the non-volatile memory device. Based on a determination that the second counter has reached a second threshold value, aspects also include initiating a refresh of a non-violate memory of the non-volatile memory device. Based on a determination that the refresh of the non-violate memory of the non-volatile memory device has been completed, aspects also include resetting the timer, the first counter, and the second counter.
