Abstract
A data processing device including a processor and a memory interface, the processor being configured to control the refreshing of a memory by the steps of: periodically forming an estimate of a current rate of decay of a memory and updating an accumulated level of decay of the memory in dependence on the estimated current rate of decay; and causing the memory interface to refresh the memory when the accumulated level of decay exceeds a predetermined threshold. The estimate may be based on a measurement of ambient temperature.
