MEMORY DEVICE AND METHOD FOR MANAGING THE SAME

Abstract:

The present disclosure relates to a method for managing a memory device including a non-volatile memory, the method comprising providing a first time-stamp to the memory device, wherein the first time-stamp is a power-down time-stamp of the memory device, storing the first time-stamp, associating the first time-stamp with at least one region of the non-volatile memory, providing a second time-stamp to the memory device, wherein the second time-stamp is a subsequent power-up time-stamp of the memory device, associating the second time-stamp with said at least one region of the non-volatile memory, determining a difference time between the first time-stamp and the second time-stamp, and, based on said difference time, performing a refresh operation of said at least one region of the non-volatile memory. A related memory device is also disclosed, as well as a specific method for measuring the off-time of a memory device.
