Method for computer-assisted operation of a memory unit and execution of application programs having redundant data storage

A method for computer-assisted operation of a memory unit, the method comprises steps of:

• encoding groups of application data sets, each application data set of a group containing data segments having identical application data for an application program and check data segments having different diversity characteristic data from a supply of possible diversity characteristic data, and then saving the encoded application data sets in the memory unit;
• retrieving the application data sets from the memory unit and then decoding the retrieved application data sets;
• when performing a first-time encoding of the application data sets in the encoding step, performing substeps of:
• generating or selecting at least one group of application data sets containing data segments having identical application data for an application program and check data segments having different diversity characteristic data from the supply of possible diversity characteristic data;
• and
• encoding and saving each application data set of the group of application data sets;
• wherein the diversity characteristic data includes an adjustment operator for adjusting the data segment generated by the decoding to the data segment before the decoding.

A method for computer-assisted repeated execution of an application program in redundant computing instances, the method comprises steps of:

• encoding groups of application data sets, each application data set of a group containing data segments having identical application data for an application program and check data segments having different diversity characteristic data from a supply of possible diversity characteristic data, and then saving the encoded application data sets in the memory unit;
• retrieving the application data sets from the memory unit and then decoding the retrieved application data sets;
• when performing a first-time encoding of the application data sets in the encoding step, performing substeps of:
• generating or selecting at least one group of application data sets, containing data segments having identical application data for an application program and check data segments having different diversity characteristic data from the supply of possible diversity characteristic data;
• and
• encoding and saving each application data set of the group of application data sets;
• retrieving, for an execution of required application data sets, each application data set of a relevant group of encoded application data sets from the memory unit and decoding each said application data set;
• checking for the existence of an error in a respective one application data set of the decoded application data sets by determining when the diversity characteristic data in the respective one application data set deviates from all said possible diversity characteristic data of a computing instance from the supply;
• executing the application program with the data segments of said each application data set of the relevant group if no said error was determined;
• and/or
• encoding, and saving in the memory unit, at least the application data sets, which due to an execution of the application program include changed or generated data segments.
