Abstract
In response to a read instruction, the confidentiality of a data entry to be read from memory is determined by referencing the state of a confidentiality flag corresponding to that data entry. If the data entry is determined to be confidential, then specified codes of the data stored in the RAM are converted into different codes, i.e., the data entry is scrambled. The data entry is then displayed using the converted codes.
