摘要：
In order to detect a power outage in a volatile data memory containing useful data units and test data units associated with to the useful data units, the associated test data unit is read along with the useful data unit when said useful data unit is read-accessed, a decision is made as to whether the useful data is corrupt or not based on the test data unit, and a power outage is identified when at least two read useful data units within a predefined number of successive read accesses are considered to be corrupt.
