description Abstract Method for computer-assisted operation of a memory unit and execution of application programs having memory checking for memory errors The subject matter of the invention is a method for computer assisted operation of a memory unit, wherein data is saved in the memory unit and the data is encoded before saving, data is retrieved from the memory unit and the data is decoded after retrieval. The memory unit is monitored for errors in that a temporal sequence of computer-assisted checking operations is carried out for the memory unit. For first-time encoding (COD) of the data, each required application data set (ADS) is generated or selected, containing check data segments (PA). For each application data set (ADS), the check data segment (PA) is occupied by count data (ZD), which characterizes the checking operation being implemented. Each application data set (ADS) is encoded and saved. For checking the data in the checking operation being implemented, after retrieving and decoding (DEC) the application data sets (ADS) respectively, an error is determined for an application data set (ADS) when the count data (ZD) characterizes neither the checking operation being implemented nor the most recent completely implemented checking operation. The check data segment (PA) of the relevant application data set is occupied by count data (ZD), which characterizes the checking operation being implemented, if no error was determined. The relevant application data set (ADS) is encoded and saved again if no error was determined. The invention further relates to a method for execution of application programs and to a computer program product. Fig. 3 | DD1 ZD RD AD V ~RE-, _,-RE| ADS-- DD1 ZD RD AD COD RE-- DD1 -DD2
