ActiveUS20080151669A1Accurate measurementReduce generationRead-only memoriesDigital storageRetention memoryEngineering
Systems and methods are disclosed that facilitate extending data retention time in a data retention device, such as a nanoscale resistive memory cell array, via assessing a resistance level in a tracking element associated with the memory array and refreshing the memory array upon a determination that the resistance of the tracking element has reached or exceeded a predetermined reference threshold resistance value. The tracking element can be a memory cell within the array itself and can have an initial resistance value that is substantially higher than an initial resistance value for a programmed memory cell in the array, such that resistance increase in the tracking cell will cause the tracking cell to reach the threshold value and trigger refresh of the array before data corruption / loss occurs in the core memory cells.
